[Mailman-Users] Outbound smtp email problems (qmail problems)

For those who may have been tracking this saga:

My Mailman-SMTP problems stemmed from my non-root system accounts having no 
ability to resolve localhost to my machines IP address...because there was 
no non-root read permission set for /etc/hosts.  (My 'telnet localhost 25' 
tests were all previously run from the root account, and as soon as I 
finally ran it from a non-root account, then the problem root cause finally 
reared its simple, little, ugly head.)

Yes, this is a terribly disgusting thing to learn that I spent so much 
blood, sweat, and tears on such a silly system flaw.
