Just by coincidence, I wrote FAQ 4.62
and it kind of addresses this.

What you need to do is pick one canonical url host and email host and
set DEFAULT_URL_HOST and DEFAULT_EMAIL_HOST to those values (probably
'www.host.domain' and 'host.domain') and run fix_url to fix all your

Then you need to put a rewrite in your web server to rewrite all the
other host names to the canonical one (maybe only for mailman).

In Apache, this might look like:

RewriteEngine on
RewriteCond %{HTTP_HOST}    !^www\.host\.domain [NC]
RewriteCond %{HTTP_HOST}    !^$
RewriteRule ^/mailman(/.*)  http://www.host.domain/mailman$1   [L,R]

Of course the one big issue I see is the following. Can you access
www.host.domain from your side of the router? If not, then you have a
problem and probably the best you can do is set VIRTUAL_HOST_OVERVIEW
= Off if that is an option.
