[issue4142] smtplib doesn't clear helo/ehlo flags on quit

[Don Dwiggins]

New submission from Don Dwiggins <ddwiggins at advpubtech.com>:

Found on Windows, running Python 2.4.3.

SMTP.login() and SMTP.sendmail set one of the attributes ehlo_resp or
helo_resp to whatever the server responded (only if they're not already
set).

SMTP.quit() doesn't clear these attributes, so on the next connection,
the HELO/EHLO commands won't be sent; this will cause problems with some
servers (MDaemon in my case).  The fix is obvious, and a workaround
would be to clear the attributes in the instance before calling login
(or sendmail where authentication isn't needed).
