B4X

Send a Raw IMAP Command (Binary)

Demonstrates the Chilkat Imap.RawCommandBd method, which sends raw IMAP command bytes and receives the raw response bytes. The first argument is a BinData holding the command — without an IMAP tag or trailing CRLF, which Chilkat supplies — and the second is a BinData that receives the response.

Background: This is an escape hatch for rare server extensions the API does not otherwise expose. It is intended for commands with a single-line response that do not change Imap object state such as the selected mailbox or message count. For everyday operations, use the dedicated methods, which parse responses and maintain object state for you.
