In my own defense, I would say that where this message _does_ occur in
the document, it is always in response to _conclusive_ evidence of
ratware. Namely:
- After a numeric HELO (HELO your.ip.address, for instance)
- After a HELO with your FQDN, not the sender's,
- After no HELO.
Given that we *know* conclusively that we are dealing with ratware at
this point, I don't see a need to give the spammer any more information
(i.e. recipe for getting around it).
But saying "message was delivered by ratware" after failing to verify
the sender address (especially when it is due to your own problem) is,
well, misleading.
BTW, I think your attribution is not up to snuff. I wrote the above,
not "exim-users-admin".
