[Mailman-Users] Mailman stopped delivering mail

[Eric Evans]

Mark, thanks very much for your suggestion.  I did read the suggested page 
and tried the little diagnostics suggested there.  They indicate no 
discrepancies, and yet I still can't get Mailman to deliver any 
messages.  I also modified our resolv.conf as suggested, but still no 
success.  It seems clear that Mailman is, for some reason, unable to 
resolve hostnames.  Why is it that other applications running on this same 
server can resolve hostnames but Mailman can't?  What is different about 
Mailman's method of resolving hostnames?  BTW I also tried reinstalling 
Mailman (in the process upgrading from 2.1.2 to 2.1.5) and I still can't 
get Mailman to work.

Thanks,
Eric
