(.NET Core C#) Forward by Attaching the Existing Email to a New Email

Demonstrates how to forward an email by attaching the email to a new email. This example uses the AttachEmail method, which is new in Chilkat v9.5.0.87.

This example reads an email from an IMAP server, attaches the email to a new email, and sends the new email.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Read the 1st (most recent) email in an Inbox.
Chilkat.Imap imap = new Chilkat.Imap();

// Connect to an IMAP server.
imap.Ssl = true;
imap.Port = 993;

// Login

// Select an IMAP mailbox

// Fetch the email at the last sequence number.
