Lua

Create a Reply Email

Demonstrates the Chilkat Email.ToReply method, which generates a reply email with updated header and body fields so it can be sent as a reply. Attachments are excluded from the reply, but attached messages are included. The source email is not modified. This example creates a reply and prints its MIME.

Background: Replying is more than swapping sender and recipient: the To is set from the original's reply address, the subject gets an Re: prefix, the original text is quoted, and threading headers (In-Reply-To, References) are added so mail clients group the conversation. ToReply assembles all of that, leaving a message you can edit and send. Dropping attachments is the usual reply convention — you rarely echo the sender's files back to them.
