I recently had a tmda challenge for a domain Im hosting trigger a email relay test. Though this is to be expected (and my systems passed with flying colors), the response from those who initiated the relay test (nortel networks) brings up an interesting point.
I think this guy doesn't really understand the point behind tmda, but if his suggestion saves me a relay test, Id be happier (not that Im not happy now!)
Any comments?
Thanks.

The messages we received were TMDA responses for spams that were sent out with From: addresses forged to be in our spamtrap.
We try to distinguish "true" spams in our spamtrap from bounces and viruses. Unfortunately, the TMDA response looks like a valid message rather than a bounce, and triggers the relay tester.
Sorry about that.
TMDA should do its rejections inline wherever possible (so they'd only be seen by the spammer's tools), and format them like NDRs (null return addresses ala RFC821).
