Simply change the name you apply and check for to something else of your own
choice. X-junk, X-Smelly, X-brackafrax ... whatever you have NOT seen in common
use.
- optionally strip that choice on the way in - BEFORE anything that might add
it.
- optionally strip it again on the way out in router/transport sets.
That way, no one else sees your choice. Which makes it hard to forge.
Better yet - use an acl_m class variable, and you won't need a header at all.
CAVEAT:
- an acl_m variable 'lives' only until the last delivery has been completed. It
does not travel into the final mailstore and is not part of what the end-user
receives and displays on their MUA.
- a header OTOH, 'lives' as long as any copy of the message lives - 'anywhere',
including - on the end-user's workstation.
So if you need to do debugging days or months after the fact, a header may be
preferable to perusing old logs for the acl_m value ... if you even remembered
to log it!
HTH,
Bill
