[Mailman-Developers] Trying to get started developing Mailman

Sat Jul 25 13:37:18 CEST 2015

Thanks for the help. I have double-checked my postfix configuration to make
sure it is like yours, but my mail to the list still bounces.
mail.log looks like this when I try to send a message to the list (in this
case named mailman at augusta.net):

Jul 25 07:20:39 augusta postfix/pickup[4387]: C40252006E5: uid=1000
from=<thomas at augusta>
Jul 25 07:20:39 augusta postfix/cleanup[4488]: C40252006E5: message-id=<

(delivered to mailbox)
Jul 25 07:20:39 augusta postfix/qmgr[4388]: D113C2006F1: removed

essentially, bounced because of unknown user
and the actual bounce notification in /var/mail/thomas is similar:

<"lmtp:[127.0.0.1]:8024"@localhost> (expanded from <mailman at augusta.net>):
    unknown user: "lmtp:[127.0.0.1]:8024"

--C40252006E5.1437823239/augusta.net
Content-Description: Delivery report
Content-Type: message/delivery-status

Reporting-MTA: dns; augusta.net
X-Postfix-Queue-ID: C40252006E5
X-Postfix-Sender: rfc822; thomas at augusta
Arrival-Date: Sat, 25 Jul 2015 07:20:39 -0400 (EDT)

Final-Recipient: rfc822; "lmtp:[127.0.0.1]:8024"@localhost
Original-Recipient: rfc822; mailman at augusta.net
Action: failed
Status: 5.1.1
Diagnostic-Code: X-Postfix; unknown user: "lmtp:[127.0.0.1]:8024"

I have tried with and without a user on my system named "mailman", either
way the message bounces if sent to mailman at augusta.net, but with a user it
goes through if sent to mailman at localhost (when there is a user), which I
find odd. I can send mail to other users fine with <name>@augusta.net.
Thanks for any further assistance! Sorry for the newbish questions.
