Well, first thing first, postfix is a MTA, not POP3/IMAP server.

Config dovecot to listen IMAPS port and secure by SSL/TLS those connections.

Suggest: http://wiki.dovecot.org/SSL

change files:
/etc/dovecot/dovecot.conf
/etc/dovecot/conf.d/20-imap.conf

enable imaps "protocol"
and config it, set correct certificates. You will need to generate those certificates.

You needn't subscribe it by a trusted certificate authority (no CA import).
