Just don't open those ports.  Then they only work locally.  For imap, 
that works well with the local imap webmail software.

Why should a local squirelmail or roundcube server have to go through 
SSL to the local dovecot server?

But this is why you DON'T turn off the firewall and apply the right rules.
