AFAIR exim3 could listen on some other port than 25 too.

This behaviour is even in exim4, from exims POV it's a totally new
message, so it gets a new ID assigned. (Your are talking about the IDs
exim uses for identifying the messages in spool, logs, ..., not about
the Message-ID-Header.)

The current exim(4) logs the Message-ID-Header, this can be used to
track a message in the logs, but I'm not sure if it's true for exim3
already:

But you see, the exims "internal" id changes as stated above.

You need to scan the message from inside exim to see it as one ID per
message. But with exim3 it's not possible, in exim4 it should, using the
acls.
