Attached is 2 diff files that enable some minimal IMAP
mailbox support for the roundup-mailgw module.

Basically they mimic the do_pop() commands, only using
imaplib instead of poplib.

For me, the ssl support doesn't work. I'm not sure why,
because if I type the commands at the prompt, it works.
But when I run them with the script, it gives me
'socket.sslerror: The read operation timed out'.

mailgw.diff contains the addition of do_imap(), and
then roundup_mailgw.py contains the additions to the
command-line tool.

But the normal IMAP works fine.
