rejecting on wrong informations in HELO/EHLO saves me lots of spam.
That's a half-baked idea at best, given that you're violating a MUST NOT in the SMTP specification. Plus, how do you judge "wrong"? Hotmail and MSN both fail to use their FQDNs in their HELO arguments---technically that's wrong. I suppose you reject all hotmail.com email?
