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.

Swift

func chilkatTest() {
    var success: Bool = 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.
    let imap = CkoImap()!

    // Connect to an IMAP server.
    imap.ssl = true
    imap.port = 993
    success = imap.connect(hostname: "imap.example.com")
    if success == false {
        print("\(imap.lastErrorText!)")
        return
    }

    // Login
    success = imap.login(login: "myLogin", password: "myPassword")
    if success == false {
        print("\(imap.lastErrorText!)")
        return
    }

    // Select an IMAP mailbox
    success = imap.selectMailbox(mailbox: "Inbox")
    if success == false {
        print("\(imap.lastErrorText!)")
        return
    }

    var numEmails: Int = imap.numMessages.intValue

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

    let email = CkoEmail()!
    success = imap.fetchEmail(headerOnly: false, msgId: numEmails, bUid: false, email: email)
    if success == false {
        print("\(imap.lastErrorText!)")
        return
    }

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

    print("\(email.subject!)")

    // Create a new email.  The email we just read will be attached to this email.
    let eForward = CkoEmail()!

    eForward.add(to: "Joe", emailAddress: "joe@example.com")

    eForward.fromAddress = "matt@somewhere.com"
    eForward.fromName = "Matt"
    eForward.subject = "This is an email with another email attached."

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

    // Attach the email.
    eForward.attach(email: email)

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

    // We could send (forward) the email..
    let mailman = CkoMailMan()!

    mailman.smtpHost = "smtp.example.com"
    mailman.smtpUsername = "myLogin"
    mailman.smtpPassword = "myPassword"
    mailman.smtpPort = 587
    mailman.startTLS = true

    success = mailman.sendEmail(email: eForward)
    if success == false {
        print("\(mailman.lastErrorText!)")
        return
    }

    success = mailman.closeSmtpConnection()
    if success != true {
        print("Connection to SMTP server not closed cleanly.")
    }

    print("Mail Sent!")
