Next, if you are going to configure a quarantine SCL threshold, a spam quarantine mailbox must
be specified. This will enable all messages at or greater than the quarantine threshold to be sent
to a configured email address. To achieve this, it is recommended that a separate Exchange
Server database be large enough to hold quarantined messages. Then create an Active Directory
user account with an Exchange mailbox and create a profile for it.

4. Next, configure the Content Filter agent with the email address of the spam quarantine mailbox
configured earlier. You can do that by running the following command:
Set-ContentFilterConfig -QuarantineMailbox spam@ExchangeExchange.local
5. Finally, configure the SCL threshold for messages and continually monitor the spam quarantine
mailbox. In here you can use the Send Again option in Outlook to release legitimate messages by
resending the original message. You can also monitor the agent log for false positives and adjust
the SCL threshold accordingly. To diagnose why a message is flagged as spam, you can review
the anti - spam stamp and anti - spam report on the message by looking at the Internet headers in
Outlook 2007. Here is an example of an anti - spam report:
X-MS-Exchange-Organization-Antispam-Report: SenderOnRecipientSafeList
X-MS-Exchange-Organization-SCL: -1
X - MS - Exchange - Organization - SenderIdResult:
PASS Junk E - Mail Filter
Because anti - spam is a two - prong approach, on the client side, the Outlook Junk E - Mail filter evaluates
whether a message should be treated as a junk email based on factors such as time, time message
was sent, message content, and other data collected by the Exchange Server anti - spam filters.
