[Cialug] Mailman configuration question

[Daniel A. Ramaley]

The domain name was set within Mailman. I played with sendmail and got 
it to always use "lists". But the problem remained. Finally, to solve 
it i looked at DNS. The machine had an A record of "netreg" and a CNAME 
alias of "lists". I set both to be A records and the problem went away. 
Evidently foreign servers when sending to the machine try to 
canonicalize the domain name and that is what was messing things up.
