The protocol should actually be "imaps" I think. If this doesn't change
anything either, probably you should try to turn on the debug messages
of JavaMail itself (which can be done using a system property, or
directly in the code JwmaSession.java).
The JavaMail debug messages will be in the containers System.out
and might indicate what could be going wrong.
