[Mailman-Users] Help with list mail not sending

[Trevor Bekolay]

Hello,

I've gone through all the steps in
http://wiki.list.org/display/DOC/4.78+Troubleshooting-+No+mail+going+out+to+lists+members
but I'm still unable to get email to send out on my mailing list.

I'm using Postfix and Mailman 2.1.12 on an Ubuntu server. Most things work fine:
- Users get subscribe/unsubscribe and welcome emails
- Web interface works as expected, can create new lists and the like
- Emails sent to the list get added to the archive, viewable through
the web interface

However, two kind of major things don't work:
- Emails sent to the list don't get sent to subscribers
- Members can't view the subscriber list through the listinfo page

The fact that welcome emails get sent but mails to the list don't
baffles me. Here are the Postfix logs from a welcome email that gets
sent properly:

And here are the Postfix logs from an email that Mailman tries to send
to list subscribers:

Yet the first email appears in my inbox and the second one doesn't.

Any help would be greatly appreciated!
