Enumeration

Automatic (0)
Implicit (1)
Explicit (2)
None (3)

The SMTPSSLStartMode property may have one of the following values:


Automatic	If the remote port is set to the standard plaintext port of the protocol (where applicable), the adapter will behave the same as if SMTPSSLStartMode is set to Explicit. In all other cases, SSL negotiation will be implicit (Implicit).
Implicit	The SSL negotiation will start immediately after the connection is established.
Explicit	The adapter will first connect in plaintext, and then explicitly start SSL negotiation through a protocol command such as STARTTLS.
None	No SSL negotiation, no SSL security. All communication will be in plaintext mode.
