Enum Encryption 

pub enum Encryption {
    Auto,
    StartTls,
    Tls,
    None,
}

How the connection is protected.

Variants

Auto

Implicit TLS on port 465, STARTTLS everywhere else when the server offers it. The right answer almost always, and the default.

StartTls

STARTTLS, and refuse to continue if the server does not offer it.

Tls

TLS from the first byte, the way port 465 works.

None

Plaintext. Only sane against a mail catcher on localhost.
