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

$imap = New-Object Chilkat.Imap

# Turn on session logging:
$imap.KeepSessionLog = $true

# Connect to an IMAP server.
# Use TLS
$imap.Ssl = $true
$imap.Port = 993
$success = $imap.Connect("imap.someMailServer.com")
if ($success -ne $true) {
    $($imap.LastErrorText)
    exit
}

# Login
$success = $imap.Login("myLogin","myPassword")
if ($success -ne $true) {
    $($imap.LastErrorText)
    exit
}

# Select an IMAP mailbox
$success = $imap.SelectMailbox("Inbox.RubyMail")
if ($success -ne $true) {
    $($imap.LastErrorText)
    exit
}

# Get the complete set of Uids for email in the selected mailbox.
$messageSet = $imap.GetAllUids()
if ($imap.LastMethodSuccess -ne $true) {
    $($imap.LastErrorText)
    exit
}

# Set the Deleted flag for each message.
# (ExpungeAndClose must be called to finalize the delete.)
$success = $imap.SetFlags($messageSet,"Deleted",1)
if ($success -ne $true) {
    $($imap.LastErrorText)
    exit
}

# Alternatively, the Deleted flag may be set for each UID
# individiually, but this is less efficient:

$n = $messageSet.Count
for ($i = 0; $i -le $n - 1; $i++) {
    $success = $imap.SetFlag($messageSet.GetId($i),$messageSet.HasUids,"Deleted",1)
    if ($success -ne $true) {
        $($imap.LastErrorText)
        exit
    }

}

# Expunge and close the mailbox.
$success = $imap.ExpungeAndClose()
if ($success -ne $true) {
    $($imap.LastErrorText)
    exit
}

# Display the session log.
$($imap.SessionLog)

# Disconnect from the IMAP server.
$success = $imap.Disconnect()
