Close a Persistent SMTP Connection

See more SMTP Examples

Demonstrates the Chilkat MailMan.CloseSmtpConnection method, which explicitly closes the current SMTP connection. Before closing the socket, Chilkat sends the SMTP QUIT command so the server can end the session cleanly. This example opens a connection and then closes it.
