changing the hostname in mailman

[Justin Zygmont <jzygmont solarflow dyndns org>]

I am having a hard time changing the hostname in mailman.  When I log in 
and select: tend to pending moderator requests, each link is using 
porky.devel.redhat.com as the host name.  I've removed every instance of 
this under /var/mailman but it's still there when I go back.  Does anyone 
know how this can be changed?

thanks..
