If you want to beef up your security a bit, consider signing your email messages (and eventually encrypting them).
Most people today send unsigned email messages. A signed message provides a greater level of security than an unsigned message because it informs the receiver that the message has not been tampered with since it left the sender. However, a signed message offers a lower level of security than an encrypted message.
