This is exactly why you do not want a PIX to "fix" smtp for you.

Seriously, if you want to see what's going on, get tcpdump and look at
what's going over the wire as obviously the client gets confused by
something the pix says, and it's not obvious from the logs (at least to
me) what that might be.
