I get them all the time; most of them are EXEC2STATE DROP and stuff like
that from either misconfigured Ex2k installs thinking I am a routing group
or *nix boxes doing other stuff.

This is why I've been wanting to find out the IP of the offending box, but
nothing matches up in my logs... I do see port 25 blocks in the fw log, but
not at the same time that the smtpevt shows up...

Has anyone run across this yet? In the event viewer, I am seeing this daily:

Event ID 17220
"An unknown SMTP command"
Source: smtpevt

I am running ISA on a member server, and behind it on another server is
Exchange 2000.
I can't seem to find out any information on this error?
