Render an Email to MIME Bytes in a BinData

Demonstrates the Chilkat MailMan.RenderToMimeBd method, which renders an Email object as MIME bytes and appends the result to a BinData, without sending the email. This example renders a message into a BinData and prints the byte count.

Background: This is the binary version of RenderToMime. A BinData holds raw bytes, which is the right container when you want the rendered MIME as binary — to write it directly to a file or socket, hash it, or hand it to another API expecting a byte buffer — rather than as text.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var success = false;

//  Demonstrates the MailMan.RenderToMimeBd method, which renders an Email object as MIME
//  bytes and appends the result to a BinData (without sending the email).

var mailman = new CkMailMan();

//  Build the email to render.
var email = new CkEmail();
email.Subject = "Rendered email";
email.From = "alice@example.com";
email.AddTo("Bob","bob@example.com");
email.Body = "This message is rendered to MIME bytes in a BinData.";

//  Render the MIME into a BinData.
var bdMime = new CkBinData();

success = mailman.RenderToMimeBd(email,bdMime);
if (success == false) {
    console.log(mailman.LastErrorText);
    return true;
}

console.log("Rendered MIME size (bytes) = " + bdMime.NumBytes);
