Try posting a complete executable failing example?  If you're not going to
track it down, you need to pass on enough info so someone else can <0.9
wink>.  MS SMTP servers in my experience follow the most restrictive
possible reading of the protocol specs, and will just sit there if you e.g.
so much as include an extraneous blank.

Also be clear about which version of Python you're using, and which OS.
smtplib.py has changed a *lot* since 1.5.1 (have you tried 1.5.2?).
