B4X Requires Chilkat v11.0.0+

Delete All IMAP Email

Demonstrates two ways to delete all email in a mailbox on an IMAP server. B4X

Dim success As Boolean = False

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

Dim imap As ChilkatImap
imap.Initialize("imap")

'  Turn on session logging:
imap.KeepSessionLog = True

'  Connect to an IMAP server.
'  Use TLS
imap.Ssl = True
imap.Port = 993
success = imap.Connect("imap.example.com")
If success = False Then
    Log(imap.LastErrorText)
    Return
End If


'  Login
success = imap.Login("myLogin", "myPassword")
If success = False Then
    Log(imap.LastErrorText)
    Return
End If


'  Select an IMAP mailbox
success = imap.SelectMailbox("Inbox.RubyMail")
If success = False Then
    Log(imap.LastErrorText)
    Return
End If


'  Get the complete set of Uids for email in the selected mailbox.
Dim messageSet As ChilkatMessageSet
messageSet.Initialize
success = imap.QueryMbx("ALL", True, messageSet)
If success = False Then
    Log(imap.LastErrorText)
    Return
End If


'  Set the Deleted flag for each message.
'  (ExpungeAndClose must be called to finalize the delete.)
success = imap.SetFlags(messageSet, "Deleted", 1)
If success = False Then
    Log(imap.LastErrorText)
    Return
End If


'  Alternatively, the Deleted flag may be set for each UID
'  individiually, but this is less efficient:
Dim i As Int = 0
Dim n As Int = messageSet.Count
Do While i < n
    success = imap.SetFlag(messageSet.GetId(i), messageSet.HasUids, "Deleted", 1)
    If success = False Then
        Log(imap.LastErrorText)
        Return
    End If

    i = i + 1
Loop

'  Expunge and close the mailbox.
success = imap.ExpungeAndClose
If success = False Then
    Log(imap.LastErrorText)
    Return
End If


'  Display the session log.
Log(imap.SessionLog)

'  Disconnect from the IMAP server.
success = imap.Disconnect
