The most secure operation is when the sender and recipient both use the LESecure.com web interface to compose and read messages. The message stays on the LESecure.com servers and does not need to traverse multiple e-mail servers.
Minimize your exposure if security is ever breached by keeping the amount of sensitive data on the server to a minimum.
Periodically empty the trash folder. Click on the arrow next to the trash folder, and then ’empty trash’.
Sent messages are kept by default. This can be disabled in ‘user settings’ if not needed. If it is desired, periodically delete unnecessary messages.
