Append MIME and Set the IMAP Internal Date

Demonstrates the Chilkat Imap.AppendMimeWithDateStr method, which uploads a MIME message while explicitly setting the server-side internal date. The first argument is the mailbox, the second is the MIME text, and the third is an RFC 822 date/time string (for example Fri, 10 Jul 2026 20:15:30 GMT). This example uploads to Archive with a specific internal date.

Background: The IMAP internal date is mailbox metadata, distinct from the message's own Date header. It is normally the time the message arrived, and it is what the server uses for SINCE and BEFORE date searches. Setting it explicitly matters when migrating or importing messages, so imported mail keeps its original chronology instead of all appearing to arrive at import time.
