SmtpSSLRequireTrustedCA Metabase Property (IIS 6.0)
The SmtpSSLRequireTrustedCA property enables verification of a certificate that a remote host gives you when you connect to it. It makes sure this certificate is in your trusted certificate root on your computer. If not, it ends the SSL session and the handshake is rejected.
You can configure this property at the following locations in the IIS metabase.
For general code examples, see Code Examples to Configure Metabase Properties.
