I have Courier-MTA and maildrop configured on a RHEL3 box, everything's working great. All users are virtual LDAP users, all Maildirs are owned by an account named vmail. My users are allowed to create server side filters using a Squirrelmail plugin. In order to autoforward their mail to another account I have them create a rule like this:

if (/^From:.*/) { cc "!anot...@another.domain.com" }

This seems to work great except for one issue. When maildrop resends the message to anot...@another.domain.com, it adds this header:

Return-Path: <vma...@myrealdomain.com>

This causes delivery failures, etc to go to vmail (which I have aliased to postmaster) rather than to the sender. Anything I can do to suppress that header or maybe I'm just doing things completely the wrong way? Thanks.
