Cannot send mail via client

Post by illidan5 » 2020-10-24 13:13

I had my hmailserver account setup, with local domain I have made
I am using windows and running the services on my PC (not windows server)

first of all my test logs:
Test: Collect server details
hMailServer version: hMailServer 5.6.7-B2425
Database type: MSSQL Compact

Test: Test IPv6
IPv6 support is available in operating system.

Test: Test outbound port
SMTP relayer not in use. Attempting mail.hmailserver.com:25...
Trying to connect to host mail.hmailserver.com...
Trying to connect to TCP/IP address 5.189.183.138 on port 25.
Received: 220 mail.hmailserver.com ESMTP.
Connected successfully.

Test: Test backup directory
ERROR: Backup directory has not been specified.

Test: Test MX records
Trying to resolve MX records for mydomain.com...
ERROR: MX records for domain mydomain.com could not be resolved

Test: Test local connect
Connecting to TCP/IP address in MX records for local domain domain mydomain.com...
ERROR: MX records for local domain makechange.com could not be resolved

Test: Test message file locations
Relative message paths are stored in the database for all messages.

Test: Test IP range configuration
No problems were found in the IP range configuration.

I am using C# program code as the client, it is also sits on the same windows as the hmailserver I will show you the code (not all of it, just the important mail sending part.).

Code: Select all

class SmartMassMailer
{
    static IConfigurationRoot Configuration { get; set; }
    static SmtpClient SmtpClient { get; set; }
    
    static SmartMassMailer()
    {
        var builder = new ConfigurationBuilder()
            .AddJsonFile("appsettings.json");
        Configuration = builder.Build();

        SmtpClient = new SmtpClient(Configuration["smtpSettings:host"])
        {
            UseDefaultCredentials = false,
            Credentials = new NetworkCredential(
                Configuration["smtpSettings:username"],
                Configuration["smtpSettings:password"])
        };

        Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);
    }

    static void SendEmail(string recipientEmail, string subject, string bodyHtml)
    {
        var msg = new MailMessage
        {
            From = new MailAddress(
                Configuration["fromEmail"],
                Configuration["fromName"]),
            IsBodyHtml = true,
            Body = bodyHtml,
            BodyEncoding = Encoding.UTF8,
            SubjectEncoding = Encoding.UTF8,
            HeadersEncoding = Encoding.UTF8,
            Subject = subject
        };
        msg.To.Add(recipientEmail);
        SmtpClient.Send(msg);
    }
The appsetting.json:

Code: Select all

{
  "fromName": "from_name",
  "fromEmail": "domainname@mydomain.com",
  "emailSubject": "email_subject",
  "emailHtmlTemplate": "email-template.html",
  "recipientsExcelFile": "recipients.xlsx",
  "smtpSettings": {
    "host": "my_local_ip ? ", <--- I have tried multiple combinations here, not sure what to use, nothing works tough
    "username": "domainname@domainname.com",
    "password": "password"
  },
  "delayBetweenEmailsMilliseconds": 7000,
  "startRow": 1
}
basically it takes the information from the json file into the program, such as host name etc.

now I tried on cmd the following :

Code: Select all

> telnet localhost 25
   
  220 mail.mydomain.com ESMTP
Also :

Code: Select all

>netstat -na | find ":25" | find "LISTENING"
  TCP    0.0.0.0:25             0.0.0.0:0              LISTENING
going into https://www.myip.com/ and typing the ip shown on cmd:

Code: Select all

>telnet *my_ip* 25
Connecting To *my_ip*...Could not open connection to the host, on port 25: Connect failed
also:

Code: Select all

>telnet mail.hmailserver.net 25
Connecting To mail.hmailserver.net...Could not open connection to the host, on port 25: Connect failed
trying to run the program with my local ip shown on the website inside 'host' in json results in:
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond *my_ip*:25

trying to put 5.189.183.138 in 'host' :
'The SMTP server requires a secure connection or the client was not authenticated. The server response was: SMTP authentication is required.'
also inside hmailserver -> ip range -> require smtp authentication, everything is unchecked except 'external to external email adderess'

trying something else can result in no host found..
Hope I provided enough information for you to help me figure this out

You are confusing things and relating to things that are not actually related to the problem.

For example, this has no relevance to anything:

Code: Select all

>telnet mail.hmailserver.net 25
Connecting To mail.hmailserver.net...Could not open connection to the host, on port 25: Connect failed
Why you trying to connect to mail.hmailserver.net ? (It probably doesnt exist but certainly has no relevance to anything).

This (from the server):

Code: Select all

> telnet localhost 25
   
  220 mail.mydomain.com ESMTP
is no surprise (doesnt really prove anything beyond confirming Hmailserver service is running). You have effectively said "can I connect to myself?"

However, this:
going into https://www.myip.com/ and typing the ip shown on cmd:

Code: Select all

>telnet *my_ip* 25
Connecting To *my_ip*...Could not open connection to the host, on port 25: Connect failed
tells you that your machine is not contactable from the WAN. This is likely to be due to firewall and/or port forwarding not set in your router, or even whether you have the necessary DNS records setup. See the Documentation for help - it has a LOT of things covered. In particular: https://www.hmailserver.com/documentati ... om_outside

Work through that - you will find your answers in that page.

I have opened port 25 on firewall following this guide https://www.avoiderrors.com/how-to-open ... -firewall/

still not change... telnet *my_ip* 25 -> same error
running the program -> same error

I checked my domain with intoDNS , everything is ok except :
MX Error MX Records Oh well, I did not detect any MX records so you probably don't have any and if you know you should have then they may be missing at your nameservers!

In cmd i did :
>nslookup -type=mx mydomain.com
Server: ns2-cache.hotnet.net.il
Address: 213.57.22.5
makechange.com
primary name server = elsa.ns.cloudflare.com
responsible mail addr = dns.cloudflare.com
serial = 20******
refresh = 10000 (2 hours 46 mins 40 secs)
retry = 2400 (40 mins)
expire = 604800 (7 days)
default TTL = 3600 (1 hour)
so I guess if I dont have my mx records set I cannot send mails? how do I solve this?
by the way im using wifi on my computer which has hmailserver and the client.
also can you tell me if I filled the smtp setting in the json correctly ? who do I put on 'host' for example ?

If you are attempting to connect to hMailServer by using an External Public IP Address such as I see you referring to in your Postings not only do you have to open Port 25 in Windows Firewall but you must also Forward Port 25 on your Router Firewall to the Local IP Address of the PC running hMailServer.

You don't necessarily need any MX Records in DNS to be able to send email. MX Records in DNS are set so you can receive email from other email servers.

It worked :D

I have sent mails to my yahoo mail 2 times, one for the core address and other to the alias , both have reached and not in spam folder

how can I make sure my email will NOT land on spam folder? I am planning on sending large amount of emails, but with a delay to prevent this

can some of you guys send me your emails for testing maybe? :) I want to make sure it works perfectly

There is SO MUCH more to running a mailserver than simply installing the software and opening ports on your router (with instruction).

You need a valid SSL certificate, and not a self signed one
You need SPF, DKIM and DMARC records
You need RDNS to match your local host name
You need valid DNS records - not simply an IP address
You need ....MUCH MORE

When you think that you have all of the bits that you think is possible, start running some online tests, especially including Open Relay tests.

A lot of inexperienced users unwittingly become Open Relays, without understanding what that is, or why it has happened. These are EXACTLY what spammers try to find and exploit (normally really easy to exploit due to low level of knowledge of users who operate them).

Providing a email address to an inexperienced user, who is likely to become a Open Relay though ignorance, really is a lot like leaving a sign saying 'back in two weeks, key under mat' on the front door of your house.

Anyhow, try these online tests, and make sure that you at least pass them all

https://en.wikipedia.org/wiki/Sender_Policy_Framework
SPF allows the receiving mail server to check during mail delivery that a mail claiming to come from a specific domain is submitted by an IP address authorized by that domain's administrators.[3] The list of authorized sending hosts and IP addresses for a domain is published in the DNS records for that domain.
https://en.wikipedia.org/wiki/DomainKey ... ified_Mail
DKIM allows the receiver to check that an email claimed to have come from a specific domain was indeed authorized by the owner of that domain.[1] It achieves this by affixing a digital signature, linked to a domain name, to each outgoing email message. The recipient system can verify this by looking up the sender's public key published in the DNS. A valid signature also guarantees that some parts of the email (possibly including attachments) have not been modified since the signature was affixed.


Basically, email is reputation based. These tools help you protect your reputation. SPF says "emails from X domain are only allowed to be sent by servers Y and Z". DKIM is a digital signature that the receiving server validates by comparing the signature to a dns txt record. If these things don't exist, its assumed the sending server is malicious because spammers (often) don't use these tools, because they can't be spoofed.

Check the email which went to your SPAM Folder. There may be indications on it which say why. You may have to look at the email's Internet Message Headers to find some of the indications. The email went to your SPAM Folder because the receiving email Server or the email Client which received the email thought it looked like SPAM. Perhaps your IP Address is on a SPAM Blacklist, etc. Some of the reason why the Receiving Email Server might believe your email looked like SPAM are because of the things mattg was indicated to you that you needed to have set up such as SPF and DKIM, etc.

Additionally, if the test email you sent to yourself you sent through hMailServer, then you should also look at hMailServer's Logs to see why it marked your test Email as SPAM. hMailServer though does not deliver email to your SPAM Folder. Your email Client does that. hMailServer just either deletes the email or marks it as SPAM depending on how you set up hMailServer to treat email it identifies as SPAM. Again if hMailServer identified your Test Email as SPAM, then hMailServer Logs should show the reason.

where did you buy your domain name?
They probably host your DNS settings...

I checked my domain with intoDNS , everything is ok except :
MX Error MX Records Oh well, I did not detect any MX records so you probably don't have any and if you know you should have then they may be missing at your nameservers!
so I guess if I dont have my mx records set I cannot send mails? how do I solve this?
Did you create an MX record?
Just 'cause I link to a page and say little else doesn't mean I am not being nice.

Did you create an MX record?
As I said above I did not buy the domain, it is local.

about the MX record, im not sure, I remmber following some steps about MX records but I dont quite remmber, can you tell me the proccess of adding MX records? I have been told it is not mandatory for mail delivering so I guess I skiped it

Email is reputation based. If you attempted to connect to my server without mx, spf, and other minimum reputational items, you would be instantaneously firewall banned forever. Because you're a spammer, or at least behave like one.

Technically, you don't need any of that stuff to send mail, but practically, very few servers will accept mail from you without them.

Ok so what happened now? I was sending myself emails which was not in spam folder and now after sending mails I tried to test again and it appeared on spam folder


so where do I start? how do I set up all these? I tried to set up DKIM and you can see my question above, and even IF I do all this, I will be able to send emails without redirected to spam folder? or I may have been blacklisted? where can I check this ?

You can check blacklist status here: http://multirbl.valli.org/

As far as the rest, you can start by getting a domain, then setting up mx.

Read some tutorials. There's a bunch in the User-submitted tutorials forum. Give it a try first. Then come back with questions.

Keep in mind, even with SPF, DKIM, etc, there's still no guarantee your mail will reach recipients. That depends on the receiving server's rulesets for receiving mail. There's an old cliche on this forum, but its as true today as the first time it was said - if your messages aren't getting through to xyz mail server - ASK THEM WHY, not us. Only they know the reason. Sometimes they even tell you the reason. We can only help you generally. Only the rejecting server can tell you specifically why your mail is rejected or sent to spam.

seems I am not listed.. strange..
anyway, you tell me to start with getting a domain, I HAVE A DOMAIN, a local one, I dont pay for it, I have my local SMPT server, thats what hmailserver is for right? I have been sending mails with it, my only problem is that now my test emails marked spam
so can you can you answer my question here?
Also I wanted to setup DKIM following this guide

https://www.hmailserver.com/forum/viewtopic.php?t=29402

what do I do in step 2? whre is the DNS portal? this is a local domain im not using goDaddy or somthing like that... so how do I change my DNS records ?
also should I set up MX records before doing this or? doesnt matter ?

If by Local Domain you mean a Domain you set up only on hMailServer, SPF and DKIM only validate Registered Public Domains. If you only have this 'Local Domain' only set up on hMailServer, SPF & DKIM validation should always fail and Receiving Email Servers potentially can mark the email you send as SPAM. Read the documentation on SPF and DKIM to understand how SPF and DKIM work.

If you want to send email on the Internet you need to get a Registered Public Domain (Domains are cheap).

Ok so what is 'public' domain ? some company gives you a domain to run on their server and you pay for it.
Im saying, I have my own server, I want to use my own domain, why do I need to pay for someone to store my domain on their server?
so what do you mean by 'public' ? can I make my local domain public ? infact, paying for a domain means having a local domain on someone elses server, isnt it?

does MX records require public domain aswell ?

Because you need a means of hosting DNS records accessible to the world. That's how other servers will check your spf/dkim/dmarc records.

I am confused, what do I need to pay for? what those business do that I cant do on my own? they are bussiness after all, which sells you a service, why I have to use it ?

by the way, I have tested my local ip on the black-list and I am listed on 9 out of 187 tests, checked one of them and it blocked on maillisting

You need a public domain. You can’t host a public domain yourself. Entering a domain in hmailserver is not enough.

There are thousands of domain resellers. Depending which top level domain (e.g. .com, .net, .org) and reseller you choose, you have to pay more or less money.

So get a public domain, create MX, SPF and DKIM records and host hmailserver on your server.

If you're not hosting your own DNS server, then you will probably need to pay someone to do it for you. Do you have your own DNS server accessible to the internet?

NO DNS = NO SPF/DKIM/DMARC

Right. But even if your hosting your own DNS servers (like I do) you have to pay for the domain itself. But explaining the whole DNS here is a little bit too much.

So use a subdomain of a domain you already own.

I don't know enough about DNS to help you any further. If you're hosting your own DNS you already know way more than me about it. You should know how to make your dns internet facing.

I pay $10/year for a dyn dns service that allows me to create the text records I need to make SPF, etc work. $10/year is not the end of the world.

Because you aren't authorized to register Domains that the World (Internet) knows about. The Internet does not know your 'Local Domain'. You actually haven't even set up a Domain on your Local Network. You really don't have a 'Local Domain'. The 'Local Domain' as you call it seems to be the one you named within hMailServer which isn't creating a Domain. The function of adding a Domain in hMailServer is to merely tell hMailServer what established Domain you are going to use with hMailServer. There are situations where you can set up a Domain the Internet does not know about but your usage of this 'Local Domain' isn't one of those situations. Therefore when a Receiving Email Server tries to check your SPF and DKIM it can't find your 'Local Domain' because it doesn't exist on the Interenet. Hence the term 'Local Domain'. You could host your own DNS Server but you don't know how to do this and neither do I. Your Domain also does not run on the Domain Registrar's Server. It may be defined on a Name Server which you don't have. It is far simpler just to buy a Domain on a Domain Registrar who will host the DNS Server for you. As I said earlier, too, Domains are cheap to buy. One of my 5 Domains only costs around $15.00 (US) per year if memory serves me correctly.

if you comply to the terms you can always use https://freedns.afraid.org/ to get a subdomain from one ot the provided domains
in some domains they let you put in MX records .. and be aware that they have their own definition of public and private domains regarding who can add pointers in them

Iβ€˜m not illidan5. :wink: I have a perfectly running hmailserver setup.

For my cheapest .de domain I just pay 1.44 € / year. (0.12 € / month)

You can get free domains here: https://www.freenom.com/

But because they are free and so get used by a lot of spammers, their reputation is really bad.

Ok thanks everyone for clarifying, thinking of it, domain is not even a problem, I could use temprary email domain and extand it every time, I have tried it
the thing is im using this for mostly studying and testing, ofcourse if things get more serious in the future I will use propar domain and setup

so lets say im using one of those free domains you provided, I just have to put it in hmailserver domain list? and I will be able to setup MX, SPF etc?...


thirdly, Im not even sure it is domain issue, running this test http://multirbl.valli.org/ on my domain name gives no blacklist while running the the ip shows 8 blacklisted (out of 187 tests)

Image

here it says my mail is blacklisted (one of the tests) the thing is, I havent done this test before so I cant compare (My mails did not end up in spam folder in the begining, now after sending quite alot of mails , it does.).

You REALLY need to read the technical knowledge requirements at the end of this
https://www.hmailserver.com/documentati ... quirements

From the questions that you ask, you don't seem to have the REQUIRED skill set or knowledge base required to run a mail server

A mail server run by a NOOB is dangerous, as they ONLY ever end up spewing spam, either by intent, or because they are easily compromised
Just 'cause I link to a page and say little else doesn't mean I am not being nice.

I try to explain what happens when someone trys to send an email to the domain you've registered.

Let's say you've registered the domain "example.com" at a domain name registrar (e.g. GoDaddy is a domain name registrar).

All domain name registrar (also known as domain reseller) I know, provide their own nameserver (also known as DNS server).

These nameservers keep the information about your domain. So if you want to add/change/delete records, you can do this at your domain name registrar.

For receiving email you need at least two records:
  1. An A-record which points to the IP address of your server (e.g. mail.example.com -> 93.184.216.34)
  2. A MX-record which points to this A-record (e.g. example.com -> mail.example.com)
You see, hMailServer hasn't done anything so far.

But hMailServer needs to known, that it is responsible for the domain "example.com". So you need to add this domain to hMailServer.

Let's say I'm sending an email to info@example.com. My mailserver is doing the following things:
  1. Get MX-Record of "example.com" -> mail.example.com *
  2. Get A-Record of "mail.example.com" -> 93.184.216.34 *
  3. Connect to "93.184.216.34" and deliver email to you mailserver
* These two steps are done with DNS (automatically):
  1. Ask root name server for IP addresses of nameservers of "com"
  2. Ask nameservers of "com" for IP addresses of nameservers of "example.com"
  3. Ask nameservers of "example.com" for MX and A records
For sending email, you should also provide SPF and DKIM records. This improves your reputation and lowers the chance for your emails to got to the spam folder.
These records you also have to store in the nameserver of your domain name registrar.

That's not going to help him when he's policy blocked.

I doubt his mail is even going to spam. Policy block usually means instant reject and disconnect. For me it does, anyway.

well you are wrong, im not blocked, my emails goes to spam folder (Atleast at my email using yahoo.) I dont know about others.
it was not the case before and now it does, im trying to figure out what caused that
so I have been told here I cant setup DKIM and SPF without buying a domain so there is nothing I can do my current domain ?

Why do you use this domain? Doesn't seems like it's your domain.

OK I'm wrong. I know... completely shocking.... :lol:

I DO reject PBL. Many others do as well. I guess I was wrong about the big providers. Instead of blocking, they send it to spam.

Remember, email is reputation based. Its up to the receiving server to decide what to do based on their perception of your reputation. In my opinion, every address on the PBL is a bot and can safely be rejected without even receiving the message to inspect for spamminess. Furthermore, I also firewall block every single one I come across so they never even get a second chance to connect to my hmailserver.

https://www.spamhaus.org/pbl/

And no, for the 30th time, you need public dns/domain to run an email server even when you're only sending and not receiving.

I looked here

http://resellers.freenom.com/knowledgeb ... icle&id=44

it says "you should already be using DNS" , whats the meaning of this? when setting up DNS on freenom i need to use my own IP ? because it asks for ip

ok I got a domain from freenom but they wont send me a varification mail yet... anwyay after getting the domain I want to be using for mailing

I looked here

http://resellers.freenom.com/knowledgeb ... icle&id=44

it says "you should already be using DNS" , whats the meaning of this? when setting up DNS on freenom i need to use my own IP ? because it asks for ip
I am not an expert on this but when you get a Domain from a Domain Registrar (ex. GoDaddy), usually the Domain will be registered and if you don't want to use the Domain as a website it can be 'Parked'. This Domain (ex. at GoDaddy) is set up in for example GoDaddy's DNS Servers. You then need to set up in for example GoDaddy's DNS Servers an A-Record which will point to the IP Address of your hMailServer Email Server. Then you are able to set up for example GoDaddy's DNS an MX Record which will point to the hostname of the A-Record you created which points to the IP Address of your hMailServer.

How you create these DNS records you would have to find out from your Domain Registrar. In GoDaddy for example, GoDaddy gives you access to their Zone File Editor. A Zone File is where the entries are which set these Records up for the DNS Servers. My Domain Registrar is GoDaddy and I learned how to do this by looking at the Zone File for my Domain (which is now Parked) and looked at how I was set up to use their Email Server and just substituted my own hostnames and IP Addresses for hMailServer. There is more to all this such as setting up your SPF, PTR, etc in DNS Records but this is the basics. I can't give you a complete tutorial.

Some Domain Registrars may set up these DNS Entries for you.

Well, that's the price if you can't afford a paid domain.

A lot of mailservers test if the sending domain has MX-records as a part of spamtests.

Pages like https://www.mail-tester.com/ can tell you, what's probably causing your mails going to spam folders.

how do you set up reverse-DNS ?
[/quote]

https://freedns.afraid.org/ it lets you choose a public domain and add a subdomain to it, now how can I use it? there are option to add MX and TXT but im not sure how to do it, anyone who knows this tool can guide ?

For mx and a records: Get a domain!
Being listed in spamhaus PBL is a showstopper in most cases. See palinka's answer:

You can go to https://www.spamhaus.org/lookup/ and see why your IP is listed. Most likey is that your ISP doesn't want you to send mails with your IP.
IPs of my ISP are also listed with this reason:
It is the policy of 1&1 Versatel Deutschland GmbH that unauthenticated email sent from this IP address should be sent out only via the designated outbound mail server allocated to 1&1 Versatel Deutschland GmbH customers using SMTP-Auth. To find the hostname of the correct mail server to use, customers should consult the original signup documentation or contact 1&1 Versatel Deutschland GmbH Technical Support.
So I have to use the relay server of my ISP.

Ask your ISP if they can set a reverse record for you IP. This records should be the same like in hMailServer -> Settings -> Protocols -> SMTP -> Delivery of e-mail -> Local host name (your a record should also be the same).

So to summarise
#1 You DON'T HAVE the required knowledge to run a mail server
#2 You are too cheap to purchase a real domain name at only a handful of dollars per year
AND
#3 you admit to wanting to send, not receive which is the EXACT profile of a SPAMMER

Time to find a new hobby
(please uninstall hmailserver first)
Just 'cause I link to a page and say little else doesn't mean I am not being nice.

yes I understand most IPs ends up in that list, I looked at spamhaus, basiclly every IP which is not a public mail server is listed there
So I have to use the relay server of my ISP.
how you do so? you just use the relay server IP? where can you find it? (dont forget that I allowed port 25 in my ISP administration panel.)


by the way I managed to register on freenom, but once I complete my domain purchase it says :

Attention!
Some of your domains could not be registered because of a technical error. These domains have been cancelled:

*mydomain*

... so annoying, everything was fine untill suddenly my emails started to go to spam folder :(

I successfully registered a .tk domain yesterday for testing...


Why do you only want to send and not receive mails? What's the purpose of your C# program? I think mattg could be right.

Looks like mattg could be right about being a SPAMMER. See what I found out about the .tk Domain:

https://en.wikipedia.org/wiki/.tk

wikipedia:

Abuse

In 2006, McAfee conducted a survey in which they claim out of the 95 percent most trafficked web sites, .tk domains were twice as likely as the global average to be used for "unwanted behaviours", including scams such as phishing and spam.[5] However, in 2008 McAfee reported that the threat of scams like phishing and spam was significantly reduced with .tk and that other top level domains such as .com and .net were much more used in such scams.[6]

A 2011 report by the Anti Phishing Working Group blamed Tokelau's bad reputation on the registry Dot TK. It acquired the right to operate the top level domain and is responsible for the current free registration system. .tk domains logged 2533 of 11768 (~21.5%) total phishing attacks in the second half of 2010 Internet-wide.[7]

This notation is a little confusing as in 2006 McAfee makes it seem like .tk was responsible for twice the global average used in unwanted behaviours but in 2011 states .tk domains sere significantly reduced with .tk with other TLDs .com and .net being more used in such scams.

Also have to realize this is 2020 now which is a long time since 2006 or 2011.

OP didn't wrote anything about .tk domain. I did. And I just registered one because OP said he wasn't able to register a domain at freenom.com.
So I can't quite follow your argument.

yet mailtester still gives me a score of 0/10 , strange cus I know yahoo are very strict about filtering emails

Anyway this time I am going to test every now and then to see when it will drop back to spam folder (I assume it will)

I stand corrected. I didn't notice it was your statement about the .tk domain.

Email are already in spam folder again.. before even sending any mail..

anyway I decided to purchase a domain from GoDaddy... and I did so.. I got 1 year of use for 1$

so this is where I am at:

Image

I want to add MX records, SPF, DKIM also I may need A records and TXT ? let me know.. I want to make sure it is perfectly setup this time
can you help with filling the data ? what do I input ? I red the docs on godaddy but remmber I am using hmailserver and my client program.. so I want to make sure I put the correct data (like hmailserver hostname?).
some of you said you are using godaddy so I guess it wont be a problem from here on

By the way.. I still dont get it, it is simple when you got a web portal made for you and you just need to input the records, but things are happening in the backend while you do so, thats what I ment when I said I want to do so by myself, without a 'portal' provided to me (as you can see by the way im sending the emails.).
also there are domains that cost thousands of dollars... I mean why do I need to pay godaddy for the 'name' ? why they "own" the name? thats what I want to understand, who are they to charge for domain names like they own the internete ? I also saw an option to put my domain for sell (and pay godaddy a fee) ... lets say I want to come up with my own domain without the help of godaddy, what prevents me from doing so ?

a VERY brief summary
ICANN https://www.icann.org/resources/pages/w ... 2-02-25-en is the organisation that coordinates IPnumber and Nameing conventions (DNS gTLDs/TLDs) which will be availiable on the internet.
you can apply with ICANN and become an ICANN-accredited registrar so you can "register" domain-names. ( and then some registrars wholesale registration possibility to other companys like ISPs, hosting companies, operators, webbhotels and others )

IF you havent got an agreement with ICANN or business with a registrar or a sub-provider you cant register domainnames. ( thats the answer to your question "what prevents me from doing so" )

You can "come up with" any domainname but if you want to use it on the internet.. you use services provided by businesses on the internet to "register" it which is more like a rental agreement because you pay a yearly fee for usage as long as you want to use it, now you have to remember that internet is actually just a businessagreement between operators to carry traffic between them, and every resource used costs money and the providers can charge for their services.. and for the internet to ACTUALLY work there are some things that needs to be coordinated like the fact that if you want a domainname.. someone has to put resources in play for it to ACTUALLY work..
for more info you could always google with questions like: "why does domain names cost money"


If "you come up with" a name that you think are "the bomb", just register it with a registrar and feel free to put it "up for sale" to the highest bidder... you just have to pay the rent first yourself to get it working... ( it is a common business to register interesting name and try to get someone else to pay a shitload of money for it, it has been around since the 90s )
