(PoC) Batch sending with delay (PoC)

Post by SorenR » 2020-08-14 18:05

1: Create account "mailman@mydomain.tld"
2: Create account rule for above; If Message size > 0 Run function mailman
3: Create folder on server (hMailServer) to hold XML files
4: Modify parameters:

Code: Select all

    Const XMLDIR      = "C:\hMailServer\Events"
    Const From        = "Carrot top"
    Const FromAddress = "agent.orange@acme.inc"
5: Copy sample XML file to "C:\hMailServer\Events\mailman.xml"
6: Compose message and send to "mailman@mydomain.tld" with subject: "mailman|10|30|Have a nice day with Looney Tunes"

mailman = mailman.xml
10 = 10 recipients in a batch
30 = 30 seconds delay between batches
"Have a nice day with Looney Tunes" is the new email subject

Recipients are added as BCC thus not visiable. The "official" recipient of the email is the "mailman@mydomain.tld" account.

This is Proof of Concept code, it works but can probably not be used in production until further errorhandling has been added.

This code comes as is and is intended as a framework to be built on!

Sample XML file with recipients

Code: Select all

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
  <Address>Barnyard Dawg, barnyard.dawg@acme.inc</Address>
  <Address>Bosko, bosko@acme.inc</Address>
  <Address>Bugs Bunny, bugs.bunny@acme.inc</Address>
  <Address>Daffy Duck, daffy.duck@acme.inc</Address>
  <Address>Elmer Fudd, elmer.fudd@acme.inc</Address>
  <Address>Foghorn Leghorn, foghorn.leghorn@acme.inc</Address>
  <Address>Granny, granny@acme.inc</Address>
  <Address>Hector the Bulldog, hector.the.bulldog@acme.inc</Address>
  <Address>Honey Bunny, honey.bunny@acme.inc</Address>
  <Address>Lola Bunny, lola.bunny@acme.inc</Address>
