Sounds like you have some sort of basic networking problem, a Jail in and 
of itself won't be blocked.  I'd first check to see if you can get a 
connection from within the jail host server to the IMAPS port on the other 
machine.  Use telnet or opennssl's s_client to see if you can get a 
connection open.  I assume the dovecot server and jail have separate IPs?

If so then try the same thing from within the jail.  If both of those work 
then I'd check your PHP setup and make sure that you have the appropriate 
PHP modules installed, and that they support SSL.
