Is there any reason you need an encrypted connection when sending mail
on the localhost?  This just creates unnecessary overhead and is
usually avoided if the connection is not over public networks.  It's
trivial to add a secondary listener to Postfix's master.cf that
accepts SquirrelMail/localhost-only email submissions unencrypted on
another port.

If you really need it, SquirrelMail version 1.5.2 supports it.

FWIW, although port 465 is deprecated, I'm not sure it (postfix's
smtps service) is going anywhere anytime soon.
