from my past experience with debugging login problems (adjust for pop3
instead of imap - my problem was using IMP with imap login).

I was able to capture with just a few slight adjustments...

captured successful login via 'telnet localhost 143'
# tcpdump -w /tmp/imp-imap.good -i lo -s 0 'port imap'

captured unsuccessful login via 'imp' at the moment the 'admin' tried to
do it's thing
# tcpdump -w /tmp/imp-imap.tcpdump -i lo -s 0 'port imap'

and then 'tethereal -r /tmp/imp-imap.[tcpdump|good] showed me the
difference...turns out - even though IMP is configured to send
imap/notls, admin login is encrypted.
