' This example assumes 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 = Await imap.ConnectAsync("imap.someMailServer.com")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Login
success = Await imap.LoginAsync("myLogin","myPassword")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' First examine the already subscribed mailboxes.
Dim refName As String = ""
Dim wildcardedMailbox As String = "*"

' Alternatively, the ListMailboxes method can be called to list all mailboxes (both subscribed and unsubscribed).
Dim mboxes As Chilkat.Mailboxes = Await imap.ListSubscribedAsync(refName,wildcardedMailbox)
If (imap.LastMethodSuccess <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


Dim i As Integer
For i = 0 To mboxes.Count - 1
    Debug.WriteLine(mboxes.GetName(i))
Next
Debug.WriteLine("----")


' Sample output.

' INBOX
' INBOX/recent
' INBOX/misc
' INBOX/misc/solutions
' ...
' Outbox
' Deleted Items
' Sent Items
' Drafts
' Junk E-mail
' Trash
' Sent
' Templates

' Let's unsubscribe to "INBOX/misc/solutions".
success = Await imap.UnsubscribeAsync("INBOX/misc/solutions")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
