Subject: [Exim] Question about $message_id vs $MESSAGE_ID under exim filters
Hi!

Exim is v3.34 under Solaris 8

I have discovered an oddity here, and don't understand why it is happening.

I have a system filter defined, which causes a pipe of the message out to
another facility.

The problem is that the $message_id within the filter does not agree with the
environment variable $MESSAGE_ID passed to the pipe. They are the same, except
the ENV var has an 'E' prepended to it.

ie
$message_id = 18gvwl-0006uM-00 (filter)
$MESSAGE_ID = E18gvwl-0006uM-00 (pipe)

Can someone tell me why this is happening, and if it's supposed to do that? I
can easily code around it, but it seemed wonky to me. The other env vars all
appear OK.

Thanks!
