	Mailman doesn't care about these sorts of things itself.  The MTA 
(sendmail, postfix, Exim, whatever) will probably care, and the web 
server (e.g., apache) may care.

	But Mailman itself doesn't know anything about DNS, nor does it 
use DNS internally.  By the time the messages get to Mailman, all the 
DNS-related stuff will already have been done by the MTA.  By the 
time the users connect to the Mailman web interface, the web server 
will have done all the other DNS-related stuff.  Mailman will dump 
outgoing messages on the MTA, which will then care about using DNS to 
deliver those messages.
