Ensure 'Enable sender ID agent' is configured

TinggiLevel 1Otomatisexchange

Deskripsi

The Sender ID agent is an antispam agent enabled on Exchange servers that perform the Edge Transport server role. Sender ID tries to verify that every e-mail message originates from the Internet domain from which it claims to have been sent. Sender ID checks the address of the server that sends the message against a registered list of servers that the domain owner has authorized to send e-mail. Prints compliant when the Sender ID agent is Enabled and SpoofedDomainAction is Reject. 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.
