  1. SSL/TLS (implicit encryption) is the most secure way to communicate with the server. Encryption is mandatory, and it is established at the beginning of the SMTP session.
  2. STARTTLS (explicit encryption) is a way to upgrade a plaintext connection to an encrypted one. Encryption is optional and is initiated by your email program before logging in.
