[Mailman-Users] new trouble with existing lists

[backdoc]

	Problem description:

I can no longer subscribe to or send mail to my lists.

	Here's some detail.

 From the standpoint of being able to use the mailing lists (subscribe, 
post messages, etc), the lists had been working for several weeks. 
Then, spontaneously, all of the normal list server tasks quit working 
except for the web interface.  Attempting to subscribe to a mailing list 
results in a page that says a "confirmation has been sent ...".  But, I 
never receive that confirmation mail.

I have looked at all of the logs in /mailman/logs to see if I could see 
any references to my attempts to subscribe to the list.  But, I do not. 
    /var/log/messages does not show any references to Mailman either.

My mail server is Postfix.  It seems to operate normally in every way.

	Some possible clues:

I don't really have any strong suspicions that point to a particular 
culprit.  I don't generally muck around with my server except to keep 
the installed software up to date via portupgrade.  I don't really 
remember if the lists not working coorelates to running portupgrade. 
But, I don't think so.

Due to the fact that I own 2 domains and the domain name for the box is 
not the same domain name of the list I have created the lists for, there 
was a minor issue regarding the wrong URL showing up on the web 
interface portion of Mailman.  It was showing the box domain name as 
opposed to the list domain name.  The incorrect URL did not appear to 
have an adverse affect.  But, it was potentially confusing for users. 
So, I made a few attempts to correct it by altering the mm_cfg.py file. 
  In spite of some good suggestions here on the mailman-users list, I 
never resolved that problem.  Again, I can't associate Mailman breaking 
with attempts to fix the URL problem.

	What additional info can I give you to help you help me?

That's about all that I can think of to shed light on the problem.  Not 
seeing anything in the log files, I don't really know how to backtrace 
the problem?  Even though I don't feel like I broke it by editing the 
mm_cfg.py file or running portupgrade, I'm sure that I have somehow 
broken it.

Any suggestions would be very much appreciated.

TIA,
Darren
