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

Dim imap As New Chilkat.Imap

// Connect to an IMAP server.
// Use TLS
imap.Ssl = True
imap.Port = 993
Dim success As Boolean
success = imap.Connect("imap.someMailServer.com")

End If

// 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.PeekMode = 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.
Dim numEmails As Int32
numEmails = imap.NumMessages

Dim mset As New Chilkat.MessageSet

// Indicate that mset contains sequence numbers, not UIDs.
mset.HasUids = False

// 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.
Dim i As Int32
i = 0
While i < numEmails
    // Fetch the email by sequence number.
    Dim email As Chilkat.Email

    If (imap.LastMethodSuccess <> True) Then
        System.DebugLog(imap.LastErrorText)
        Return
    End If

    // If it is decided to move the email, add the sequence number to mset, like this:
    mset.InsertId i + 1

// If there are emails in mset to be moved, then do it..

    Dim destFolder As String
    destFolder = "Inbox/SomeOtherFolder"
    // Assuming your IMAP server supports the feature that allows for messages to be moved to another folder...
