I can confirm that this issue is still present in Python 2.5.2, 2.6.1
and 3.0.1.
The current behavior of smtplib is a clear violation of the SMTP
specification. The problem can be reproduced with code like that (stub,
pseudo code-like):
smtp = smtplib.SMTP()
smtp.sendmail('f...@example.com', 'f...@example.com', msg)
smtp.quit()
smtp.connect()
# This command does not send EHLO/HELO again, violating the spec!
smtp.sendmail('f...@example.com', 'f...@example.com', msg)
Real world bug reports due to this behavior were mostly visible with
Exim because this MTA rejects the 'MAIL FROM' if SMTP extension verbs
are used without EHLO:
