Send an SMTP RSET Command

Demonstrates the Chilkat MailMan.SmtpReset method, which sends an SMTP RSET command to the server. RSET resets the server-side state of the current mail transaction. This example opens a connection, sends RSET, and closes.

Background: During an SMTP session a message is built up across MAIL FROM and RCPT TO commands. If you need to abandon that partially-specified transaction — say an error occurred midway — RSET clears it without dropping the connection, so the same authenticated session can start a fresh message. It's a lightweight way to recover in-session rather than reconnecting.
