Postfix has lots of options to identify a returned message.
1) You can encode the unique identifier in the envelope sender
address (as an address extension). This works even when mail is
returned by a remote MTA.
2) Your unique Message ID is already returned in the bounce message.
See RFC 3462. This may or may not work for mail that is returned
by a remote MTA.
3) You can specify your own unique ENVELOPE ID via SMTP (see RFC
3461) or via the Postfix "sendmail -V" option. This ENVELOPE
ID is also returned in the bounce message. See RFC 3464. This
works only if all MTAs in the forward path implement RFC 3461.
I suggest that you study the many RFCs and non-RFC features that
Postfix already implements, before tinkering with internals.
But first, as Stan mentioned, you should describe your problem,
instead of your proposed solutions. There are likely better solutions
that already exist. I already mentioned three of them.
