Append a MIME Message to an IMAP Mailbox

Demonstrates the Chilkat Imap.AppendMime method, which uploads a complete RFC 822/MIME message to a mailbox. The first argument is the destination mailbox name and the second is the MIME text. This example obtains the MIME from an Email object and uploads it to Drafts.

Background: Use AppendMime when you already hold a message's raw source — a .eml file, a message you assembled, or one you received. Chilkat sends the text exactly as supplied, without normalizing line endings or re-encoding headers, so every header and MIME boundary is preserved verbatim. The supplied text must be plain text (no raw non-text binary bytes).
