Ensure 'Blank sender field' is configured

SrednjaNivo 1Automatskaexchange

Opis

When the Sender Filter Agent takes on messages from blocked senders or domains, the Action parameter is what is used when deciding what to do with these messages. Prints compliant when sender filter Action is Reject and BlankSenderBlockingEnabled is True. 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.
