Ensure 'SCL Quarantine' is 'Enabled'

中レベル 1自動exchange

説明

Spam Confidence Level (SCL) is a rating assigned to incoming email messages by the Content Filter agent in Exchange Server. It is a measure of the likelihood that an email is spam based on various content analysis techniques and spam detection algorithms. The SCL value ranges from 0 to 9, with 9 being the highest level of confidence that the email is spam. Ensure SCLQuarantineEnabled is set to... Prints compliant when SCLQuarantineEnabled is True and SCLQuarantineThreshold is 6 or lower. 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.
