At the moment james insert a Return-Path: null to outgoing emails. That is not correct. On outgoing emails no Return-Path should be insert.
From RFC (http://www.faqs.org/rfcs/rfc821.html):
When the receiver-SMTP makes the "final delivery" of a
message it inserts at the beginning of the mail data a
return path line. The return path line preserves the
information in the <reverse-path> from the MAIL command.
Here, final delivery means the message leaves the SMTP
world. Normally, this would mean it has been delivered to
the destination user, but in some cases it may be further
processed and transmitted by another mail system.
We have also to get sure what todo if there is allready one ( should never happen). Should we keep the header or strip it.
