Well,

It took all day, but I managed to rewrite Return-Path. Basically what I do is filter the
original message with Milter and discard it. Before discarding I take some headers
and the body from the mail and place them in a new mail and toss that to the DL with
sendmail.

The result is a clean message from the correct domain, and it should be able to pass SPF/
DKIM and all that.

Its great, because the final message that goes to the recipients is still processed by 
Zimbra as a normal DL message.


Kind regards,
