Send an Email via SMTP

Demonstrates the Chilkat MailMan.SendEmail method, which sends a single Email object through the configured SMTP server. This example configures the SMTP connection, builds a message, and sends it.

Background: SMTP (Simple Mail Transfer Protocol) is the protocol for sending mail. The typical flow is: connect to the server, authenticate, then hand over the message with MAIL FROM, RCPT TO, and DATA. SendEmail wraps all of that: you build an Email with subject, recipients, and body, and Chilkat renders it to MIME and delivers it. Modern submission commonly uses implicit TLS on port 465 (SmtpSsl = true).

//  Note: Explicitly connecting/authenticating is optional.  Chilkat MailMan automatically
//  connects and authenticates -- using the property settings above -- whenever a server
//  operation requires it.  Calling the explicit connect/authenticate methods can still be
//  helpful to determine whether a failure occurs while connecting or while authenticating.
