Append MIME with Initial IMAP Flags

See more IMAP Examples

Demonstrates the Chilkat Imap.AppendMimeWithFlags method, which uploads a MIME message and sets its initial system flags. The first argument is the mailbox and the second is the MIME text. The third through sixth arguments control \Seen, \Flagged, \Answered, and \Draft respectively — pass true to set a flag. This example uploads a message that is already marked read.
