This seems rather bizare to me. Perhaps it's normal.
I was watching the mails go out of the server as I accasionally do, when I
noticed that there were three different exim processes working on the same
message ID.
4661 ? S 0:00 /usr/sbin/exim -Mc 15a04m-0001BT-00
4664 ? S 0:00 /usr/sbin/exim -Mc 15a04m-0001BT-00
4662 ? S 0:11 /usr/sbin/exim -Mc 15a04m-0001BT-00
This seems really strange. I looked at the message and it was a large
attachment from one user on my machine to another user on the same machine.
Shouldn't exim just read the message and send to local delivery? why the
three processes?
