Delivery management

This code sample retrieves the following delivery management settings for a mail-enabled group:

  • Accept messages from
  • Reject messages from

Note

In the below code sample, the $groupParams variable represents Exchange properties of a mail-enabled group. To retrieve the properties, use the IAdmExchangeMailParametersOps::GetMailParameters method.

How
[Reflection.Assembly]::LoadWithPartialName("Softerra.Adaxes.Adsi")

# Connect to the Adaxes service
$admNS = New-Object "Softerra.Adaxes.Adsi.AdmNamespace"
$admService = $admNS.GetServiceDirectly("localhost")

# Bind to the group
$groupDN = "CN=My Group,CN=Users,DC=domain,DC=com"
$group = $admService.OpenObject("Adaxes://$groupDN", $NULL, $NULL, 0)

# Get Exchange properties
$groupParams = $group.GetMailParameters()
# The $groupParams variable represents Exchange properties of a mail-enabled group

# Get message delivery restrictions
$messageDeliveryRestrictions = $groupParams.MailFlowSettings.MessageDeliveryRestrictions

# Get list of accepted senders
$acceptMessagesFrom = $messageDeliveryRestrictions.AcceptMessagesOnlyFrom

# Accept messages only from senders inside my organization
$requireSenderAuthentication = $messageDeliveryRestrictions.RequireSenderAuthentication

if (($acceptMessagesFrom.Count -eq 0) -and (-not($requireSenderAuthentication)))
{
    Write-Host "Accept messages from: All senders"
}
elseif ($requireSenderAuthentication)
{
    Write-Host "Accept messages from: Only senders inside my organization"
}
else
{
    Write-Host "Accept messages from:"
    for ($i = 0; $i -lt $acceptMessagesFrom.Count; $i++)
    {
        $object = $acceptMessagesFrom.GetItem($i, [ref]"ADS_PROPERTY_NONE")
        Write-host "`t" $object.DisplayName
    }
}

# Get list of rejected senders
$rejectMessagesFrom = $messageDeliveryRestrictions.RejectMessagesFrom
if ($rejectMessagesFrom.Count -eq 0)
{
    Write-Host "Reject messages from: No senders"
}
else
{
    Write-Host "Reject messages from:"
    for ($i = 0; $i -lt $rejectMessagesFrom.Count; $i++)
    {
        $object = $rejectMessagesFrom.GetItem($i, [ref]"ADS_PROPERTY_NONE")
        Write-host "`t" $object.DisplayName
    }
}
