Glen, it's not a bug in exim. It's a limitation in the way that you

It's not a bugfix, add the line above, modifying the path to suit your
environment, then in that msgid_exclusions.txt, put the ip addreses
you do not want this check to be done for. For example:

192.168.*    # this is all your internal hosts
10.*            # more internal hosts
*.gpecats.com  # All of the machines you control


Note that I put the comments there to explain them, you'll need to
remove them in actual operation.

You can test it with 'exim -bh $IP' where $IP is the ip address you
want to test this acl on (you'll need to do the HELO, the MAIL FROM,
and RCPT TO and DATA).
