Ensure 'Configure sender filtering' is set to 'Enabled'

中レベル 1自動exchange

説明

Sender filtering compares a list of blocked senders that's maintained by the Exchange administrator. Note: For more information on how to create the list for blocked senders, please visit: Use the Exchange Management Shell to configure blocked senders and domains for sender filtering Note #2: Sender filtering is enabled (by default) on a system performing the Edge Transport server role. Prints compliant when sender filtering is Enabled. Run on each Edge Transport server. Run from an Exchange Management Shell or after `Add-PSSnapin Microsoft.Exchange.Management.PowerShell.SnapIn`; the audit loads the snap-in itself when Get-ExchangeServer is missing and fails if it cannot.
