Yes, modifying the zmailer group has made the 'Sender' header
disappear from the outgoing messages, and I'm no longer seeing the
bounce messages, which I assume are going back to the original
However, something new happens when 'nobody' is included in the
zmailer group. Messages that are sent to special addresses on the
server, which our crossbar.cf file catches and redirects to a special
user's account, where procmail takes over, seem to be getting the
@domain.com part of the address stripped off.
1. message CC'd to 'ABCemail@example.com'
2. crossbar.cf says that anything sent to this address is redirected
3. specialuser's procmail script archives a copy of this message, and
the archived copy has only 'ABC-123' in the CC header.
Should I expect zmailer to be editing email headers, or should I look
for another culprit?
