New submission from Piers Lauder <piers at it.usyd.edu.au>:
smtplib does not initialise the valriable 'sock' in the case where
'host' is NULL on instantiation of smtplib.SMTP.
Eg:
% python
Python 2.5.2 (r252:60911, Oct 5 2008, 19:29:17)
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import smtplib
>>> client=smtplib.SMTP('')
>>> client.sendmail('from at home', 'to at home', 'test')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.5/smtplib.py", line 676, in sendmail
if not (200 <= self.ehlo()[0] <= 299):
File "/usr/lib/python2.5/smtplib.py", line 397, in ehlo
self.putcmd("ehlo", name or self.local_hostname)
File "/usr/lib/python2.5/smtplib.py", line 333, in putcmd
self.send(str)
File "/usr/lib/python2.5/smtplib.py", line 318, in send
if self.sock:
AttributeError: SMTP instance has no attribute 'sock'
>>>
The fix is to add "self.sock = None" in __init__ if host is not set,
and then the behaviour is much more helpful:
