If you have veeery long username and/or password it encodes
it with '\n' after 80? characters.  This violates
(IMHO) smtp standard.
In following example look for \n characters.

O.

>>> from smtplib import SMTP
>>> s = SMTP('smtp.servery.cz')
>>> s.set_debuglevel(255)
>>>
s.login('veeeery.looooong.username@veeeeery.loooooong.domain',
'veeeeery.loooong.password')
send: 'ehlo shade.globe.cz\r\n'

Thanks for the bug report. This has already been fixed in
Python 2.3-CVS and the 2.2 maintenance branch. So just
upgrade to Python 2.2.2 when it'll be out tomorrow :-)
