How can I secure dovecot listening on port 143 to specific machines only?

Squirrelmail suggests using non-ssl if the imap daemon is on the same host...

Otherwise squirrelmail could use TLS but what about other clients wanting to use SSL on port 993? (sorry I don't know enough about TLS).

I use iptables so that only 127.0.0.1 can access IMAP.

Everyone else has to use IMAPS.
