(PowerShell) Secure IMAP over TLS/SSL

To communicate with an IMAP server over TLS/SSL, simply set the Ssl and Port properties. The remainder of your code is the same as with non-SSL.

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

$imap = New-Object Chilkat.Imap

# To use a secure TLS/SSL connection, set the Ssl property and the port:
$imap.Ssl = $true
# The typical port for IMAP SSL is 993
$imap.Port = 993

# Connect to an IMAP server.
$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 = $imap.SelectMailbox("Inbox")
if ($success -ne $true) {
    $($imap.LastErrorText)
    exit
}

# We can choose to fetch UIDs or sequence numbers.
$fetchUids = $true
# Get the message IDs of all the emails in the mailbox
$messageSet = $imap.Search("ALL",$fetchUids)
if ($imap.LastMethodSuccess -eq $false) {
    $($imap.LastErrorText)
    exit
}

# Fetch the emails into a bundle object:
$bundle = $imap.FetchBundle($messageSet)
if ($imap.LastMethodSuccess -eq $false) {

    $($imap.LastErrorText)
    exit
}

# Loop over the bundle and display the FROM and SUBJECT of each.
$i = 0
$numEmails = $bundle.MessageCount
while ($i -lt $numEmails) {
    $email = $bundle.GetEmail($i)
    $($email.From)
    $($email.Subject)
    $("--")

    $i = $i + 1
}

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