Send MIME Bytes from a BinData via SMTP

Demonstrates the Chilkat MailMan.SendMimeBd method, which sends an email from caller-supplied MIME bytes held in a BinData. The arguments are the from address, the recipient list (the SMTP envelope recipients), and the BinData containing the MIME. This example loads a .eml file into a BinData and sends it.

Important: When sending caller-supplied MIME, ensure the Message-ID header is unique for each message. Sending MIME whose Message-ID was previously used can cause the message to be silently discarded as a duplicate by mail servers — see chilkatsoft.com/email_duplicate_message_id.asp.

Background: This is the binary counterpart to SendMime (which takes MIME as a string). Working from a BinData is the right choice when the message's raw bytes come straight from a file, a database blob, or a network stream — it delivers them byte-for-byte with no charset conversion that could alter the original, which matters because MIME can carry binary transfer encodings.
