Send a Raw POP3 Command

Demonstrates the Chilkat MailMan.Pop3SendRawCommand method, which sends a raw command to the POP3 server and returns the server's response. The second argument specifies the charset to use if the command contains non-US-ASCII characters. This example sends the POP3 STAT command within an open session.

Background: POP3 is a simple line-based text protocol — the client sends short commands like STAT, LIST, UIDL, or RETR and the server replies with +OK or -ERR. This method is an escape hatch for issuing a command Chilkat doesn't wrap directly, or a server-specific extension. Note that the session must already be open, since a raw command assumes an authenticated connection.
