one problem about smtplib.py

[Frank Zheng]

I wrote some code to test "smtplib", but i met a problem when i call the
"login(user,pass)" of the "SMTP" object.
here are the codes:

s = smtplib.SMTP()
s.set_debuglevel(1)
s.connect('smtp.263.net') connect: ('smtp.263.net', 25)
connect: ('smtp.263.net', 25)
reply: '220 Welcome to coremail System(With Anti-Spam) 2.1 for
263(040326)\r\n'
reply: retcode (220); Msg: Welcome to coremail System(With Anti-Spam) 2.1
for 263(040326)
connect: Welcome to coremail System(With Anti-Spam) 2.1 for 263(040326)
(220, 'Welcome to coremail System(With Anti-Spam) 2.1 for 263(040326)') s.login('Frank','*****')

send: 'ehlo pc11.FutureDialChina.FutureDialChina.com\r\n'

reply: '250 8BITMIME\r\n'
reply: retcode (250); Msg: smtp.263.net
PIPELINING
SIZE 30720000
ETRN
AUTH LOGIN
AUTH=LOGIN
XVERP
8BITMIME
AuthMethod: None
Traceback (most recent call last):
File "<interactive input>", line 1, in ?
File "D:\tools\Python22\lib\smtplib.py", line 540, in login
raise SMTPException("No suitable authentication method found.")
SMTPException: No suitable authentication method found.

I read the "login" of "smtplib" , I found it has two authentication method
one is "PLAIN", the other is "CRAM-MD5", but the server's reply here didn't
chose one of these two choices. I tested several mail-servers in China, they
all just support "AUTH LOGIN". I found the Outlook use "AUTH LOGIN" and make
it as standard.

So I think smtplib maybe need do some changes, or someone has already did
this work.

Thanks
