Determines how the adapter starts the SSL negotiation with the SMTP Server.
Possible ValuesAutomatic (0)
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.|
