smtplib, auth and covad

[David Geller]

Hi,

I had been using smptlib to send email via my covad relay previously (several months ago), and it worked fine. Covad requires authentication, and this was accomplished fine with smtp.login(usrn ame, pwd).

Today when I tried the program, it stopped working. Using the smtp debug option, I determined that when

send: 'AUTH PLAIN abcdef\r\n'

I would get the exception:

smtplib.SMTPSer verDisconnected : Connection unexpectedly closed
Soooooo, it turns out that the covad mail server does not like to have the base64 username/password in the same line as the AUTH PLAIN. While it appears that the RFC2554 allows for this, covad does not (anymore).

I had to modify smtplib.login() to do the following:

send 'AUTH PLAIN'
wait for status code 334
send the base64 username/password
wait for status code 235

--------------------------------------- CODE
elif authmethod == AUTH_PLAIN:
(code, resp) = self.docmd("AUT H", AUTH_PLAIN)
if code != 334:
raise SMTPAuthenticat ionError(code, resp)
(code, resp) = self.docmd(enco de_plain(user, password),"")
-------------------------------------------------

Question: should the official smtplib be modified to allow for this situation?

(Python 2.3)

Thanks!
