Look good. I am now using a very similar layout an it seem to be working
well.

Hmmm, I though that was just for going from MX to MX. I did not realize that
it could be used for preserving info across stream_by_* calls. Of course,
since all it does is add a header, I guess I should have picked up on that.
Must be this cold ...

After a bit of a false start getting the /etc/mail/mimedefang-ip-key file in
place (a filter reload will not pick it up, you have to do a full restart
of MIMEDefang) everything seems to be working fine.

Thanks for information.
