[Mailman-Users] Installation On Separate Server Plausible?

[Carlos Williams]

I am being told that my Postfix email server can no longer run Apache
on the same physical server. The management has decided for specific
reasons that Apache can only be installed and configured on the web
server, not the mail server. The mail server will simply run Postfix /
Dovecot.

This will force me to move web mail (RoundCube) & MailMan to my web
server! My question is can I have MailMan function from scratch (no
data needs to be migrated to the new install) from my web server and
work?

My mail and web server are on the same LAN and same network/subnet,
just separate servers. They don't want IT to manage several instances
of the same application on different servers, in this case Apache.

Thanks for any input!
