NNTP Post a file

[Daniel]

Hi.

I've been trying to use Python to post a message to the newsgroup.
Here you can find the source code

import nntplib

print "start"
s = nntplib.NNTP('news.skynet.be')
s.group('comp.lang.python')
f=open('c:/temp/mymsg.txt')
s.post(f)
s.quit
print "done..."

I suppose that the problem is mymsg.txt.  Here it follows:

Could someone please tell me why Python refuses to post this?
Below is a traceback from this

start
Traceback (most recent call last):

    raise NNTPTemporaryError(resp)

Hope to read you soon. Best regards,  Daniel
