New submission from Milan Oberkirch: When using smtplib.SMTP to connect to a SMTP server the instance variables esmtp_response survives a SMTP.quit() which results in the following error:
>>> import smtplib >>> smtp = smtplib.SMTP('mail.oberkirch.org', 25) >>> smtp.starttls() (220, b'2.0.0 Ready to start TLS') >>> smtp.ehlo() (250, b'mail.oberkirch.org\nPIPELINING\nSIZE 10240000\nVRFY\nETRN\nAUTH PLAIN LOGIN\nAUTH=PLAIN LOGIN\nENHANCEDSTATUSCODES\n8BITMIME\nDSN') >>> smtp.quit() (221, b'2.0.0 Bye') >>> smtp.connect('mail.oberkirch.org', 25) (220, b'mail.oberkirch.org ESMTP Postfix') >>> smtp.starttls() Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3.4/smtplib.py", line 672, in starttls raise SMTPException("STARTTLS extension not supported by server.") smtplib.SMTPException: STARTTLS extension not supported by server. >>> While reporting this issue I found out that starttls also does not throw away any ehlo information as it should. Provided that fixing this would probably break existing code (which would only work with non-standard servers like postfix) I did not change that behaviour. ---------- components: Library (Lib) files: quit_resets_greeting.patch keywords: patch messages: 225450 nosy: zvyn priority: normal severity: normal status: open title: smtplip STARTTLS fails at second attampt due to unsufficiant quit() type: behavior versions: Python 3.4, Python 3.5 Added file: http://bugs.python.org/file36396/quit_resets_greeting.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22216> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
