Authenticate with the SMTP Server

Demonstrates the Chilkat MailMan.SmtpAuthenticate method, which authenticates with the SMTP server using the current SMTP property settings, such as SmtpUsername and SmtpPassword. It is typically called after SmtpConnect. This example connects and then authenticates.

Background: SMTP authentication is a separate step from connecting: after the EHLO handshake, the client proves its identity via the AUTH command using a mechanism the server offers (LOGIN, PLAIN, CRAM-MD5, XOAUTH2, etc.). Splitting connect and authenticate into explicit calls lets you pinpoint exactly which step fails — and hold an authenticated connection open to send many messages efficiently.
