SMTP Authentication

[Achim Domma]

Hi,

I try to authenticate via script to my mail server. I found some hints via
google, that SMTP authentication is a problem, but no solution. Using
set_debuglevel(1), I can see something like that:

send: 'ehlo [10.0.0.35]\r\n'
reply: '250-essen115.server4free.de Hello p50837A3A.dip.t-dialin.net

reply: retcode (535); Msg: 5.7.0 authentication failed
Traceback (most recent call last):

File "C:\Python23\lib\smtplib.py", line 583, in login
raise SMTPAuthenticationError(code, resp)
smtplib.SMTPAuthenticationError: (535, '5.7.0 authentication failed')

Can somebody give me a hint on how to encode the pwd? Or another way to send
mail, if the server requires authentication?

regards,
Achim

I know it says "imap4" in the URL, but Cram-MD5 authentication is the same
between several protocols, including SMTP.

Aha. Twisted is the solution for everything, right? </sarcasm>

SMTP.login() should work perfectly ok. I'd need a transcript *and* the
real username and password to debug this, though. But chances are that
the problem is at the SMPT *server* end, not the client end.

You could try to force the PLAIN login method instead of the CRAM-MD5
authentification method, by doing something like:

import smtplib
s = smtplib.SMTP("mylene.ghaering.de")
s.ehlo()
s.esmtp_features["auth"] = "LOGIN PLAIN"
s.debuglevel = 5
s.login("myusername", "mypassword")

Let me know if this helps.

Let me know if this helps.

It works fine, thanks a lot!

It works fine, thanks a lot!

So there is a misconfiguration at the server end. You might want to
inform your ISP of this.
