How to Copy IMAP Mail to another IMAP Server

Demonstrates how to copy the entire contents of an IMAP mailbox to another IMAP server. Go

    success := false

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

    imapSrc := chilkat.NewImap()

    //  Connect to our source IMAP server.
    success = imapSrc.Connect("imap.example.com")
    if success == false {
        fmt.Println(imapSrc.LastErrorText())
        imapSrc.DisposeImap()
        return
    }

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

    imapDest := chilkat.NewImap()

    //  Connect to our destination IMAP server.
    success = imapDest.Connect("mail.example-code.com")
    if success == false {
        fmt.Println(imapDest.LastErrorText())
        imapSrc.DisposeImap()
        imapDest.DisposeImap()
        return
    }

    //  Login to the destination IMAP server
    success = imapDest.Login("myLogin","myPassword")
    if success == false {
        fmt.Println(imapDest.LastErrorText())
        imapSrc.DisposeImap()
        imapDest.DisposeImap()
        return
    }

    //  Select an IMAP mailbox on the source IMAP server
    success = imapSrc.SelectMailbox("Inbox")
    if success == false {
        fmt.Println(imapSrc.LastErrorText())
        imapSrc.DisposeImap()
        imapDest.DisposeImap()
        return
    }

    //  After selecting a mailbox, the NumMessages property will
    //  be updated to reflect the total number of emails in the mailbox:
    fmt.Println(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
    sbMime := chilkat.NewStringBuilder()
    var seqNum int
    for seqNum = 1; seqNum <= 10; seqNum++ {
        sbMime.Clear()
        success = imapSrc.FetchSingleAsMimeSb(seqNum,false,sbMime)
        if success == false {
            fmt.Println(imapSrc.LastErrorText())
            imapSrc.DisposeImap()
            imapDest.DisposeImap()
            sbMime.DisposeStringBuilder()
            return
        }

        success = imapDest.AppendMimeWithFlagsSb("Inbox",sbMime,false,false,false,false)
        if success == false {
            fmt.Println(imapDest.LastErrorText())
            imapSrc.DisposeImap()
            imapDest.DisposeImap()
            sbMime.DisposeStringBuilder()
            return
        }

    }

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

    imapSrc.DisposeImap()
    imapDest.DisposeImap()
    sbMime.DisposeStringBuilder()
