[Mailman-Users] Can't change host name preference

[Mike Flaherty]

Hello,
 
I am trying to set up Mailman on a new domain.  I have done it in the past without issue, but now I have a really bizzare problem.
 
When I go to the "MYLIST mailing list administration General Options Section" page, I notice the following entry preloaded in the "Host name this list prefers for email" field...
 
syd.xobas.net
 
I have NO IDEA where this is coming from.  It is not my domain, so I replace it with my own.
 
However, when I click the "Submit your changes" button, it goes to an invalid page.  When I try again, I notice that when I hover over the button, the URL that it translates to incorporates that "syd.xobas.net" domain into the URL.
 
I looked all over my server (a vps running CentOS 5) for where that entry might be coming from.  I did find an occurance of it in 
 
/var/lib/mailman/archives/private/MYLIST/index.html
 
and
 
/var/lib/mailman/archives/private/mailman/index.html
 
But I don't know how it got there.  Where is the proper place to replace that domain with my own?
 
Thanks Much,
Mike
