Centralized aliases

You just have to arrange a so called "drop-box" ;)

A possible solution could be:

on your DMZ-mailserver you have to add one account for each domain.
In your virtusertable just add:

@yourdomain     domainaccount

On your LAN-mailserver you shall use fetchmail (you may already use
fetchmail now)

in your .fetchmailrc you shall have something like:

poll DMZ-mailserver with proto pop3 user domainaccount there with
password "hidden" is * here

That should work ;)

duplicate your aliases - unless your mailscanner box isn't set up to
relay for your domain.  I use mailscanner in front of an exchange box
and my mailscanner box doesn't know any of my users names.
