public SslProtocols SslProtocols { get; set; }
Gets or sets the enabled SSL and/or TLS protocol versions that the client is allowed to use.
By default, MailKit initializes this value to enable only TLS v1.2 and greater. TLS v1.1, TLS v1.0 and all versions of SSL are not enabled by default due to them all being susceptible to security vulnerabilities such as POODLE.
This property should be set before calling any of the Connect methods.
