Forward by Attaching the Existing Email to a New Email

See more Email Object Examples

Demonstrates how to forward an email by attaching the email to a new email.

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

.NET Core C#

bool success = false;

// 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;
success = imap.Connect("imap.example.com");
if (success == false) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Login
success = imap.Login("myLogin","myPassword");
if (success == false) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Select an IMAP mailbox
success = imap.SelectMailbox("Inbox");
if (success == false) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

int numEmails = imap.NumMessages;

// Fetch the email at the last sequence number.
// (We are assuming the Inbox has at least 1 email)

Chilkat.Email email = new Chilkat.Email();
success = imap.FetchEmail(false,numEmails,false,email);
if (success == false) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Disconnect from the IMAP server.
imap.Disconnect();

Debug.WriteLine(email.Subject);

// Create a new email.  The email we just read will be attached to this email.
Chilkat.Email eForward = new Chilkat.Email();

eForward.AddTo("Joe","joe@example.com");

eForward.FromAddress = "matt@somewhere.com";
eForward.FromName = "Matt";
eForward.Subject = "This is an email with another email attached.";

eForward.SetHtmlBody("<p>Hello, this is an email I'm forwarding to you.  See the attached email.</p>");

// Attach the email.
eForward.AttachEmail(email);

// We could save the .eml, then double-click on it to view in our mail program, such as Outlook or Thunderbird..
eForward.SaveEml("qa_output/forward.eml");

// We could send (forward) the email..
Chilkat.MailMan mailman = new Chilkat.MailMan();

mailman.SmtpHost = "smtp.example.com";
mailman.SmtpUsername = "myLogin";
mailman.SmtpPassword = "myPassword";
mailman.SmtpPort = 587;
mailman.StartTLS = true;

success = mailman.SendEmail(eForward);
if (success == false) {
    Debug.WriteLine(mailman.LastErrorText);
    return;
}

success = mailman.CloseSmtpConnection();
if (success != true) {
    Debug.WriteLine("Connection to SMTP server not closed cleanly.");
}

Debug.WriteLine("Mail Sent!");
