What you can try to do, is to have something like stunnel bind to the IMAPS SSL port and forward the traffic to the imap-uw server. The traffic between ssltunnel and imap-uw server will then be unencrypted and you can run tcpdump on it, capture the stream and then analyse it in wireshark. > There are several related problems reported on the Android bugs system > but none with an exact match of the symptoms.
