I've once had a similar problem, too. I've configured my domain and server to have an IPv4 and IPv6 address. But I forgot to add IPv6 support to hMailServer. So every time my mail clients tried to connect to my mail server, they tried via IPv6 and ran into a timeout. Some clients retried with IPv4, ...

I really like this tool for testing my mail server setup: https://www.mail-tester.com/

Not entirely true, his IP is also on http://www.spamrats.com/bl?81.174.138.141 Yes, you’re right. I don’t know which blacklists Microsoft uses. But when I got exactly this error from Microsoft I wasn’t on any public blocklist. Just on Microsoft’s internal list. For me the IP 81.174.138.141 seems to...

Virinum

No. It’s Microsoft. They have their own blocklist. Problem with Microsoft is that if someone from your subnet sends spam, Microsoft blocks the whole subnet. You can ask for delisting here: https://support.microsoft.com/en-us/getsupport?oaspworkflow=start_1.0.0.0&wfname=capsub&productkey=edfsmsbl3 Bu...

I just installed https://www.heidisql.com/ and took the dll from it’s installation folder.

Even though there are ways to use Dynamic IP Addresses for your hMailServer, ISPs are tending to add all their Dynamic IP Addresses to Blacklist Data Bases which means Receiving Email Servers might check these Blacklist Data Bases and block your email that you send making it pretty much a necessity...

I am not familiar with this Diagnostics utility [...]

It’s hmailserver’s build in diagnostic tool. mail.hmailserver.com is set as default. It’s for testing outbound port 25.

If you look further down in his first Posting you will see this statement he makes. trying to put 5.189.183.138 in 'host' : It looks like even if 'mail.hmailserver.com' wasn't in his Client Program he later substituted the IP Address of mail.hmailserver.com into his Client Program.

Virinum

Your Client Program should not be connecting to mail.hmailserver.com. This server belongs to the hMailServer.com website and is not your email server. IP Address 5.189.183.138 belongs to mail.hmailserver.com. Your client doesn't have access to any email accounts that would be hosted on this email s...

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

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.

Virinum

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 ISPs who don't want their customers to send e-mails have their IP addresses listed there. how you do so? you just use the relay server IP? where can you find it?...

Virinum

mostly due to no mx records and A records and listed on spamhaus For mx and a records: Get a domain! Being listed in spamhaus PBL is a showstopper in most cases. See palinka's answer: I DO reject PBL. Many others do as well. You can go to https://www.spamhaus.org/lookup/ and see why your IP is list...

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 ?

What is your current domain? Is it makechange.com?
Why do you use this domain? Doesn't seems like it's your domain.

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).

So for example for "user1@test.de" with the password "thisisatest" it would be: AUTH LOGIN 334 VXNlcm5hbWU6 dXNlcjFAdGVzdC5kZQ== 334 UGFzc3dvcmQ6 dGhpc2lzYXRlc3Q= ? Yes, that looks good. Do i use "user1@test.de" as my username or just user1? If you haven’t set a default domain (and you better don’t...

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 t...

Virinum

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 ...

Virinum

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, cr...

Virinum

For AUTH LOGIN you have to Base64 encode your username (email address) and password.

Virinum

No that is only the email address (and not a valid internet email address at that) password is not included (hMailserver hasn't shown passwords in logs for many years) AUTH PLAIN includes the password in the logs. AUTH LOGIN doesn’t. Just paste the Base64 String into a converter. You will see the e...

Virinum

You should change your password of your postmaster account immediately! It’s encoded as base64 in your logs (the part after "RECEIVED: AUTH PLAIN").

Virinum

You should insert a host name in the field “Local host name” and not an IP address. The best would be to use the reverse record of your IP address. In your case this is currently “ingertec.com.ar”.

What does the diagnostics page look like? It’s strange that telnet isn’t working.

Virinum

You’ve entered your own server in smtp relay settings. Delete this if you don’t need to use a relay server or input the right one.

So just to be sure I understand your problem right: You’ve written a piece of software which sends mails via Sendgrid. This works, right?

Is the hMailServer service running? Have you tried restarting the server? Any log messages?

For incoming mails from clients you can define any port you want in hMailServer. Port 25 has to be open for incoming mails from the world.

I'm trying to take all actions to avoid a similar situation in future I'm pretty sure it's not your fault and you can't do anything.

Microsoft’s block policy isn’t very clear / fair. My server is hosted at a German provider. The problem is that if someone from the ip subnet that also includes my server sends spam, Microsoft blocks the whole subnet.

Ah, sorry. My mistake. Combine CERTIFICATE.CRT and CA_BUNDLE.CRT in one file. Like copy the content from CA_BUNDLE.CRT beneath the content of CERTIFICATE.CRT and use this file as certificate file.

Virinum

Ok, thats more info I can work with.

you have to use CA_BUNDLE.CRT and PRIVATE.KEY

Virinum

The key has to match to the certificate file. You can't just create a new key file. And like I said, a CSR is not a certificate file. Please take your certificate.crt, remove the first three lines and copy the part -----BEGIN PRIVATE KEY----- ... also other code ... -----END PRIVATE KEY----- to an o...

CSR is a Certificate Signing Request. It's just the file for requesting a certificate. Have you tried this: Looks like your key doesn't match your certificate.

Okay... So you are saying that a domain name is basically a must if I understand you right. Yes. Even for relay services you need a domain.

You could do that. But your mails will definitely go to the spam folder of the recipients or don’t get accepted by the receiving mail servers.

The bounce message is generated by hmailserver. So outgoing traffic on port 25 seems not blocked for you. For a bounce message you don't need incoming port open.

You have to request an unblocking at microsoft or ask amazon to do that for you.

Virinum

Is your incoming and outgoing mail traffic routet over your VPS? Or only the outgoing?

Maybe you could send me your domain via pm?

But if I get email, than that name will not match, because it is the ip of the VPS, not my home.

Can you explain that in more detail? I don't understand your problem.

Generally the rDNS is mostly important for sending mail.

Does your router support NAT-loopback?
Does it work when you use the interal IP address in Outlook to connect to your mail server?

So I created rule on my firewall to forward request from 587 to mail server port 25. Unfortunately still I have issue... That won't help.
