Forward to Junk email folder in Exchange Server 2007 and 2010

 

To forward mails to the junk mail folder on Exchange 2007 or Exchange 2010, you must configure Policy Patrol to add an SCL value to spam mails, and then configure Exchange to forward mails with a certain SCL value to the junk mail folder:

1. In the Policy Patrol Administration console, go to the Anti-spam node. Select the spam category that you wish to forward to the junk mail folder and click Edit. In the Primary Actions select the option Accept message. In the Secondary actions, select the option Set SCL value and select the appropriate value from the list. You can also choose to increase/decrease the SCL value in case you have another program that is applying an SCL value to the email.

2. Set the SCL Threshold Actions in Exchange Server:

Exchange 2007: In Exchange System Manager> Global Settings, right click Message Delivery and go to the ‘Intelligent Message Filter’ tab. Set the required thresholds to move messages to a user’s Junk E-mail folder:

In Exchange 2010: To configure the SCL Junk E-mail folder threshold on individual user mailboxes, you must use the Set-Mailbox cmdlet in the Exchange Management Shell. You can configure the SCL delete, reject, and quarantine thresholds in two locations:

On the content filter configuration (per-transport server SCL configuration) We recommend that you set the organization-wide SCL thresholds on the content filter configuration on the Edge Transport server. If you run anti-spam agents on the Hub Transport server, set the organization-wide SCL thresholds on the Hub Transport server. By applying the same SCL thresholds across all transport servers, you can establish a consistent baseline level of SCL functionality across the organization. Over time, as you analyze the spam functionality and metrics provided by the anti-spam logging and reporting features, you can make additional adjustments to these SCL threshold configurations as needed.

On user mailboxes (per-recipient SCL configuration) You can use the Set-Mailbox cmdlet to set per-recipient SCL delete, reject, and quarantine thresholds on individual user mailboxes. As mentioned earlier in this topic, you set the SCL Junk E-mail folder threshold on individual user mailboxes by using the Set-Mailbox cmdlet. The per-recipient SCL delete, reject, and quarantine thresholds are stored in Active Directory and are replicated to the Edge Transport servers by the Microsoft Exchange EdgeSync service. The per-recipient SCL threshold configurations are used by the Content Filter agent even if you have set per-transport server SCL configurations. Therefore, if you have set per-recipient SCL thresholds, the Content Filter agent uses the per-recipient SCL thresholds for specific users instead of the SCL configuration on the Content Filter agent. For more information about how to use the Set-Mailbox cmdlet, see Set-Mailbox.

The following SCL threshold actions are available:

SCL delete threshold When the SCL value for a specific message is equal to or higher than the SCL delete threshold, the Content Filter agent deletes the message. There's no protocol-level communication that tells the sending system or sender that the message was deleted. If the SCL value for a message is lower than the SCL delete threshold value, the Content Filter agent doesn't delete the message. Instead, the Content Filter agent compares the SCL value to the SCL reject threshold.

SCL reject threshold When the SCL value for a specific message is equal to or higher than the SCL reject threshold, the Content Filter agent deletes the message and sends a rejection response to the sending system. You can customize the rejection response. In some cases, a non-delivery report (NDR) is sent to the original sender of the message. If the SCL value for a message is lower than the SCL delete and SCL reject threshold values, the Content Filter agent doesn't delete or reject the message. Instead, the Content Filter agent compares the SCL value to the SCL quarantine threshold.

SCL quarantine threshold When the SCL value for a specific message is equal to or higher than the SCL quarantine threshold, the Content Filter agent sends the message to a quarantine mailbox. E-mail administrators must periodically review the quarantine mailbox. If the SCL value for a message is lower than the SCL delete, reject, and quarantine threshold values, the Content Filter agent doesn't delete, reject, or quarantine the message. Instead, the Content Filter agent sends the message to the appropriate Mailbox server, where the per-recipient SCL Junk E-mail folder threshold value of the message is evaluated.

SCL Junk E-mail folder threshold If the SCL value for a specific message exceeds the SCL Junk E-mail folder threshold, the Mailbox server puts the message in the Outlook user's Junk E-mail folder. If the SCL value for a message is lower than the SCL delete, reject, quarantine, and Junk E-mail folder threshold values, the Mailbox server puts the message in the user's Inbox.

For example, if you set the SCL delete threshold to 8, the SCL reject threshold to 7, the SCL quarantine threshold to 6, and the SCL Junk E-mail folder threshold to 5, all e-mail with an SCL of 5 or lower will be delivered to the user's Inbox.

As you plan and deploy your strategy for adjusting the SCL threshold, it's important to understand that the Content Filter agent and the SCL Junk E-mail folder process the SCL threshold value differently. The Content Filter agent takes action on the SCL threshold value that you configure. The SCL Junk E-mail folder takes action on the SCL threshold value that you configure plus 1. For example, if you configure the Delete action to an SCL of 4 on the Content Filter agent, all messages with an SCL of 4 or greater are deleted. However, if you configure the Delete action to an SCL of 4 on the SCL Junk E-mail folder, all messages with an SCL of 5 or greater are deleted.
