Port 465 is only for old clients that do not use the STARTTLS command. Do
not use it, Mozilla will do the STARTTLS command when you tell it to use
SSL/TLS (simply don't try to be smarter than the program) before sending
the AUTH command (a good configured server will not allow AUTH without
previous STARTTLS).
Also CRAM-MD5 does not make much sense if the password is already encrypted
via SSL, except the case that you do not even trust that server (but then,
why do you use it).
