Get an Email's MIME into a BinData

See more Email Object Examples

Demonstrates the Chilkat Email.GetMimeBd method, which serializes the complete RFC822/MIME message (headers, body representations, related items, and attachments) and appends the bytes to a BinData object. This example builds a message, serializes it to a BinData, and prints the byte count.

Background: A BinData holds raw bytes, which is the right container when you want the MIME as binary rather than text — for example to write it directly to a file or socket, hash it, or hand it to another API that expects a byte buffer. It is the binary counterpart to GetMime (string) and GetMimeSb (StringBuilder).
