SSLStartMode Property

Determines how the component starts the SSL negotiation.


public SpopSSLStartModes SSLStartMode { get; set; }

enum SpopSSLStartModes { sslAutomatic, sslImplicit, sslExplicit, sslNone }
Public Property SSLStartMode As SpopSSLStartModes

Enum SpopSSLStartModes sslAutomatic sslImplicit sslExplicit sslNone End Enum

Default Value



The SSLStartMode property may have one of the following values:

0 (sslAutomatic)If the remote port is set to the standard plaintext port of the protocol (where applicable), the component will behave the same as if SSLStartMode is set to sslExplicit. In all other cases, SSL negotiation will be implicit (sslImplicit).
1 (sslImplicit)The SSL negotiation will start immediately after the connection is established.
2 (sslExplicit)The component will first connect in plaintext, and then explicitly start SSL negotiation through a protocol command such as STARTTLS.
3 (sslNone - default)No SSL negotiation, no SSL security. All communication will be in plaintext mode.
