As discussed on the list, I am unable to get the simap
mailgw to work. Based on my own code, I'm pretty sure
it's not a Python bug, and the IMAP server is set up
correctly. All I get from roundup is:
SOCKET ssl error: The read operation timed out

I'm happy to submit more debugging information if I
knew how to coax it out.

I could, if necessary, submit tcpdumps.

As was pointed out in the roundup-users mailing list response, 
the example in the documentation doesn't use SSL. IMAPS does 
use SSL. 
 
Try using plain IMAP.

I already did this, it was all documented on the list.
Testing IMAP with my IMAP server isn't an option. I can
demonstrate that IMAPS works and that it works *in python*.

OK, here's the code that roundup uses, from roundup/mailgw.py 
do_imap():

import imaplib
server = imaplib.IMAP4_SSL(server)
server.login(user, password)
if not mailbox:
    (typ, data) = server.select()
else:
    (typ, data) = server.select(mailbox=mailbox)
numMessages = int(data[0])
for i in range(1, numMessages+1):
    (typ, data) = server.fetch(str(i), '(RFC822)')

    # mark the message as deleted.
    server.store(str(i), '+FLAGS', r'(\Deleted)')

    # process the message
    s = cStringIO.StringIO(data[0][1])
    s.seek(0)
    self.handle_Message(Message(s))
server.close()
server.expunge()
server.logout()

(with a whole bunch of error checking that I've removed for brevity)

With no further information to go with, I'm going to have to close this bug 
report.
