can’t modify them even if they want to?

Yes.  The POP3 server used is referred to in the HTML
templates by the substitution keyword “SERVER”.  Hunt down
everywhere that MailMan allows the user to supply this value
through a form field.  The only place where this should
happen is in the template “t_login.htm”.  Find this
form field:

         <input type="text" name="SERVER" size="30">

And replace it with:

             <input type="hidden" name="SERVER"
               value=”popserver.mydomain.com”>

The box will now not even show up, and users will not have
the option of specifying a server.  This makes things
considerably simpler for novice users if the server
addresses are static.  You will probably want to do more
surgery than this to make your login page look reasonable.

The SMTP server used by MailMan is specified by the keyword
“OUTGOING”.  Change the form fields that set the “OUTGOING”
keyword in both “t_f_messageform.htm” and
“t_nf_messageform.htm” in order to rig the outgoing SMTP
server to something specific.
