Move Selected Emails to another Mailbox Folder

See more IMAP Examples

Downloads emails one by one in a selected mailbox, decides which emails are to be moved, and then moves the set of messages to another mailbox folder. Go

    success := false

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

    imap := chilkat.NewImap()

    // Connect to an IMAP server.
    // Use TLS
    imap.SetSsl(true)

    // Normally, when an email is downloaded, its "Seen" flag is automatically set.
    // We don't want our program to be interfering with the "Seen" flags.
    // To do this, set the PeekMode to true.
    imap.SetPeekMode(true)

    // After selecting the mailbox, the NumMessages property
    // will contain the number of emails in the mailbox.
    // When sequence numbers (not UIDs) are used to reference emails,
    // they range from 1 to N, where N is the number of messages in the mailbox.
    // This example will download the headers by sequence numbers.

    // Fetch each email and decide for each if it is to be moved
    // to a particular other mailbox.  If so, we'll add the sequence number to
    // the mset, and then move all emails in the mset to the other mailbox.
