	You probably have lists.domain.com.au set up as a CNAME alias, 
pointing to proxy.domain.com.au, right?  Well, don't do that.  The 
RFCs require that any CNAME aliases be fully resolved before the 
message is sent, which will screw up your outgoing mail.  Make 
lists.domain.com.au resolve directly to an IP address, and that 
should work for you.

	But this has absolutely nothing to do with Mailman.  This is an 
MTA/DNS problem, and there's absolutely nothing that Mailman can do 
to help.
