A properly-formed message should have a Message-ID: header, and this
will be logged on all the reception lines (ones with "<=") in the "id="
field. Use this for tracking the message across systems. in logfiles.

If you're wanting to track via some other means that you are coding
in your configuration, use $h_Message-ID:

Naturally, messages that arrive without the header make your life
difficult. The development tip has some help for this (log_selector
"msg_id_created"), but that probably isn't what you are running.
