Category: mail delivery Group: 2.1 (stable) Status: Open Resolution: None Priority: 5 Submitted By: jared mauch (jaredmauch) Assigned to: Nobody/Anonymous (nobody) Summary: need to sort by domain before submitting to MTA

Initial Comment: I have a number of (large) lists that have a number of users at the same domain, but are submitted to the MTA in chunks of 10 to insure the list performs reasonably.

The users at the same domain end up in different queue files of my MTA, and spark a large number of SMTP connections to their SMTP servers that could be minimized if the <user>@<domain> that is passed to the MTA is sorted by domain. Then I could have one SMTP transaction with them that delivers 10 messages.

I'm no python expert, but figure sorting of this type should be fairly simple, and will reduce the amount my SMTP server abuses these other SMTP servers, which will be a good thing(tm), as well as save bandwidth..
