Send a Raw SMTP Command

Demonstrates the Chilkat MailMan.SmtpSendRawCommand method, which sends a raw command to the SMTP server and returns the server's response. The second argument specifies the charset to use if the command contains non-US-ASCII characters, and the third indicates whether to base64-encode the command before sending. This example sends a raw NOOP on an open connection.

Background: SMTP is a line-based text protocol (EHLO, MAIL FROM, RCPT TO, DATA, QUIT), so a raw-command hook lets you issue anything Chilkat doesn't wrap — a server extension, or a custom step during a manual auth exchange. The base64 flag exists because some SMTP exchanges (notably AUTH challenge/response) require the argument to be base64-encoded on the wire.
