What do you mean by secure? Comms between your client and the server is
encrypted? Individual messages encrypted in transit and stored
encrypted? The best way to achieve the latter is to use PGP, but that
requires your recipients to use PGP.

Of course, however secure your e-mail system is, as soon as you send
something to an insecure system you've exposed everything!

Tony.
