Move Messages from one Mailbox to Another

If your IMAP server supports the MOVE capability, then it is possible to move messages from one mailbox (folder) to another. This example demonstrates the MOVE command using the SendRawCommand method. The IMAP MOVE Extension is documented in RFC 6851. DataFlex
