Send a POP3 NOOP Command

See more POP3 Examples

Demonstrates the Chilkat MailMan.Pop3Noop method, which sends a POP3 NOOP command to the server. NOOP does nothing except elicit a positive response, which is useful for keeping a session alive or verifying the connection is still responsive. This example begins a POP3 session and sends a NOOP.

// as shown at the bottom of this code sample.
