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

    var imapSrc = new chilkat.Imap();

    // Connect to our source IMAP server.
    success = imapSrc.Connect("imap.example.com");
    if (success == false) {
        console.log(imapSrc.LastErrorText);

    // Login to the source IMAP server
    success = imapSrc.Login("admin@chilkatsoft.com","myPassword");
    if (success == false) {
        console.log(imapSrc.LastErrorText);
        return;
    }

    var imapDest = new chilkat.Imap();

    // Connect to our destination IMAP server.
    success = imapDest.Connect("mail.example-code.com");
    if (success == false) {
        console.log(imapDest.LastErrorText);
        return;

    if (success == false) {
        console.log(imapDest.LastErrorText);
        return;
    }

    // Select an IMAP mailbox on the source IMAP server
    success = imapSrc.SelectMailbox("Inbox");
    if (success == false) {
        console.log(imapSrc.LastErrorText);
        return;
    }

    // After selecting a mailbox, the NumMessages property will
    // be updated to reflect the total number of emails in the mailbox:
    console.log(imapSrc.NumMessages);

    // The emails in the mailbox will always have sequence numbers
    // ranging from 1 to NumMessages.

    // This example will copy the first 10 messages using sequence numbers
    var sbMime = new chilkat.StringBuilder();
    var seqNum;
    for (seqNum = 1; seqNum <= 10; seqNum++) {
        sbMime.Clear();
        success = imapSrc.FetchSingleAsMimeSb(seqNum,false,sbMime);
        if (success == false) {
            console.log(imapSrc.LastErrorText);
            return;
        }

        success = imapDest.AppendMimeWithFlagsSb("Inbox",sbMime,false,false,false,false);
        if (success == false) {
            console.log(imapDest.LastErrorText);
            return;
        }

    }

    // Disconnect from the IMAP servers.
    success = imapSrc.Disconnect();
    success = imapDest.Disconnect();
