[Mailman-Users] Mailman and Sendmail debugging questions

Fri Jun 9 06:22:41 CEST 2006

Below in the /var/log/maillog file, why are the 4 posts sent to testlist-bounces?  I was assuming that there would be one post for each of the four list members (dud1,dud2,dud3,dud4).  Is it normal to see the testlist-bounces?  I have set up a mailertable on the receiving side of Sendmail that will accept all mail from domain.gov and send it to the mailman delivery agent.  On the sending side of Sendmail I do not use this mailertable and have set up a smart relay to relay the domain.gov messages to domainmta1 at domainpriv.gov and also set the Sendmail MTAHost on the send side to this same machine.  I have verified that I can send email directly from the server that I have Mailman on to this remote MTA via Sendmail.

I agree with your assessment that Mailman seems to be trying to post the message to the list members.  But, why is Mailman trying to relay through localhost.  I set up my DEFAULT_EMAIL_HOST to be domainmta1 at domainpriv.gov in my mm_cfg.py file.  The localhost will not recognize the dud1 at domain.gov address but the domainmta1 at domainpriv.gov server should.  I have not overridden the default DELIVERY_MODULE="SMTPDirect".

By the way, I am truly sorry that I am so dense on this stuff.  You are doing a great job trying to guide me through the jungle.

Your post was sent to 4 recipients.

Note: in the above and in what follows I have tried to remove (for
readability) the
<mailto:mailman.0.1149686915.2092.testlist at leowcs1.leopriv.gov> and
similar 'mailto:' links added by your MUA.

3 seconds later a single, mailman generated message was sent - maybe a
notice to the list owner?

The post is received from Mailman for 4 recipients.

Some other message is received by the MTA from root at localhost

and accepted for delivery to testlist-bounces, so it appears to be a
bounce (last 3 entries)

The original message for 4 recipients (k57DSY8Z004495) is sent to
dud3 at domain.gov (but this may refer to the bounce)

And another bounce relayed and accepted for delivery

And another 'Sent' to dud2 at domain.gov

Another set of 4 culminating in a 'Sent' to dud1 at domain.gov, but here
there is an additional entry (second of 5) which is actual delivery of
the first bounce to the mailman wrapper.

And another, now familiar set, I think the generation of the bounce of
dud4 at domain.gov plus the delivery to mailman of the second bounce.

and finally, the delivery to Mailman of the last two bounces.

So mailman is sending the post to dud1 at domain.gov, dud2 at domain.gov,
dud3 at domain.gov and dud4 at domain.gov, the MTA is accepting the post and
then ultimately bouncing all 4 addresses. This is an MTA configuration
or other issue. The MTA (Sendmail) either can't deliver to these
addresses or won't relay to them from localhost. This doesn't appear to
be a Mailman issue.
