Render an Email to MIME in a StringBuilder

Demonstrates the Chilkat MailMan.RenderToMimeSb method, which renders an Email object as MIME text and appends the result to a StringBuilder, without sending the email. This example renders a message into a StringBuilder and prints it.

Background: This is the StringBuilder version of RenderToMime. Appending into a StringBuilder is more efficient when the MIME is large or when you plan to further inspect or manipulate it — searching, replacing, or accumulating additional text — without creating extra intermediate string copies.

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.RenderToMimeSb method, which renders an Email object as MIME text
//  and appends the result to a StringBuilder (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 in a StringBuilder.";

//  Render the MIME into a StringBuilder.
var sbMime = new CkStringBuilder();

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

console.log(sbMime.GetAsString());
