Thanks for the suggestions.

Before configuring Mailman this time, I used `hostname www` and
`domainname funkYmonkeybutt.com` to set these values. I also entered the
FQDN "www.fuNkymonkeybutt.com" in /etc/hosts. (Again, pay special
attention capitalization...)

Using the python functions that you used above, gethostname() returned
"www" and gethostbyname("www") returned the system's IP address.

Mailman, though, failed to take the bait and instead used the
pretorious.net values [from a reverse-DNS of pretorious.net I suppose] in
the blue banner across the top of the cgi-bin/admin page. From somewhere -
only God knows where - Mailman found the FQDN that I had intended and used
it in the blue banner across the top of the cgi-bin/listinfo page. (The
FQDN doesn't have any of the upper-case typing that I've been using in
order to identify where Mailman is getting its info so I am still

Thanks, again.
