Append (Upload) an Email to an IMAP Mailbox

Demonstrates the Chilkat Imap.AppendMail method, which uploads an Email object to a mailbox on the server. The first argument is the destination mailbox name and the second is the Email. After a successful append, the AppendUid property holds the UID the server assigned (or 0 if none was reported). This example uploads a newly built message to the Drafts mailbox.

Background: The IMAP APPEND command lets a client add a message directly to any mailbox without sending it through SMTP — it is how "Save to Drafts" works, and how a client keeps its own copy in Sent. The initial \Seen state is governed by the AppendSeen property (or by the flag arguments of the AppendMimeWithFlags variants).
