IMAP Capability

Demonstrates how to send the CAPABILITY command to request a listing of capabilities that the IMAP server supports. A capability name which begins with "AUTH=" indicates that the server supports that particular authentication mechanism. PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

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

$imap = New-Object Chilkat.Imap

# Use TLS
$imap.Ssl = $true
$imap.Port = 993
$success = $imap.Connect("MY-IMAP-DOMAIN")
if ($success -ne $true) {
    $($imap.LastErrorText)
    exit
}

# Authenticate
$success = $imap.Login("MY-IMAP-LOGIN","MY-IMAP-PASSWORD")
if ($success -ne $true) {
    $($imap.LastErrorText)
    exit
}

# Get the list of capabilities:
$caps = $imap.Capability()
$("Capabilities: " + $caps)

# Here is an example of the string returned:
# * CAPABILITY IMAP4rev1 UNSELECT IDLE NAMESPACE QUOTA ID XLIST CHILDREN X-GM-EXT-1 
# UIDPLUS COMPRESS=DEFLATE ENABLE MOVE CONDSTORE ESEARCH UTF8=ACCEPT APPENDLIMIT=35882577
# LIST-EXTENDED LIST-STATUS

# Chilkat v9.5.0.58 introduces the HasCapability method to
# check to see if a particular capability exists:
if ($imap.HasCapability("QUOTA",$caps) -eq $true) {
    $("IMAP server supports the QUOTA extension.")
}

if ($imap.HasCapability("IDLE",$caps) -eq $true) {
    $("IMAP server supports IDLE.")
}

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