Copy an Email from One Mailbox to Another

Copies an email from one IMAP folder to another. After running this example, copies of the email will be present in both source and destination folders. 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.

    // This example copies an email from one mailbox to another.
    let imap = CkoImap()!

    // Turn on session logging:
    imap.keepSessionLog = true

    // Connect to an IMAP server.
    // Use TLS
    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: "***", password: "***")
    if success == false {
        print("\(imap.lastErrorText!)")
        return
    }

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

    var fetchUids: Bool = true

    // Get the message IDs for all emails having "Re:" in the subject.
    let messageSet = CkoMessageSet()!
    success = imap.queryMbx(criteria: "SUBJECT Re:", bUid: fetchUids, msgSet: messageSet)
    if success == false {
        print("\(imap.lastErrorText!)")
        return
    }

    // Copy the messages from "Inbox.testing.a" to "Inbox.testing.b" in one call to CopyMultiple:
    success = imap.copyMultiple(messageSet: messageSet, copyToMailbox: "Inbox.testing.b")
    if success == false {
        print("\(imap.lastErrorText!)")
        return
    }

    // Alternatively, loop over each message in the set and
    // copy each separately:
    var i: Int = 0
    while i < messageSet.count.intValue {

        var msgId: Int = messageSet.getId(index: i)
        var isUid: Bool = messageSet.hasUids

        success = imap.copy(msgId: msgId, bUid: isUid, copyToMailbox: "Inbox.testing.c")
        if success == false {
            print("\(imap.lastErrorText!)")
            return
        }

        i = i + 1
    }

    // Display the session log.
    print("\(imap.sessionLog!)")

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