You are the messaging engineer for your company. The network contains a single Exchange Server 2007 server that hosts the Mailbox server role, the Hub Transport server role, and the Client Access server role. A mail-enabled universal security group named Sales Department contains all mailbox-enabled user accounts for the sales department. You need to ensure that all messages with a Spam Confidence Level (SCL) of seven or higher sent to members of the Sales Department group are moved to the Junk E-mail folder. Your solution should not affect the junk mail filtering for other users. What should you recommend?
A.
Set the organizations spam confidence level junk threshold to six.
B.
Create a transport rule that sets the spam confidence level to zero for any message that has a spam confidence level of seven or greater, and that is intended for members of the Sales Department group.
C.
Use the Exchange Management Shell to enable the spam confidence level junk parameter and to set the spam confidence level junk threshold to seven for each member of the Sales Department group.
D.
Use the Exchange Management Shell to enable the spam confidence level quarantine parameter and to set the spam confidence level quarantine threshold to seven for each member of the Sales Department group.
Explanation:
Anti-spam agents, enabled on the Edge server, filter all messages entering the Exchange organization from the Internet. Metadata is added to filtered email. Unfiltered, legitimate messages are delivered to the recipient’s mailbox.Use the following parameters to configure anti-spam features with Set-Mailbox: AntispamBypassEnabled, SCLDeleteEnabled, SCLDeleteThreshold, SCLJunkEnabled, SCLJunkThreshold, SCLQuarantineEnabled, SCLQuarantineThreshold, SCLRejectEnabled, SCLRejectthreshold.
With the exception of the junk configuration, mailbox SCL settings are the same as those used by the Content Filter Agent. These are applied to the entire organization. Junk settings are applied to each mailbox, individually, and override any organization-wide filter configuration.
SCLDeleteEnabled, SCLJunkEnabled, SCLQuarantineEnabled, and SCLRejectEnabled have three possible values: $true, $false, and $null. Using either $true or $false, the parameter overrides Content Filter Agent settings. For a $null value, agent settings are applied.
To configure all the anti-spam settings on a mailbox:
Set-Mailbox -Identity <MailboxIdParameter> -AntispamBypassEnabled <$true | $false> -RequireSenderAuthenticationEnabled <$true | $false> -SCLDeleteEnabled <$true | $false | $null> -SCLDeleteThreshold <Nullable> -SCLJunkEnabled <$true | $false | $null > -SCLJunkThreshold <Nullable> -SCLQuarantineEnabled <$true | $false | $null > -SCLQuarantineThreshold <Nullable> -SCLRejectEnabled <$true | $false | $null > -SCLRejectthreshold <Nullable>
To configure John’s mailbox to bypass all anti-spam filters and have messages that meet or exceed SCL Junk Email threshold of 5 delivered to his Outlook Junk Email folder:
Set-Mailbox -Identity John -AntispamBypassEnabled $true -SCLJunkEnabled $true -SCLJunkThreshold 5
To configure anti-spam features on multiple mailboxes, pipe Get-Mailbox cmdlet to Set-Mailbox.
To enable the SCL quarantine threshold of 7 on all mailboxes in the Users container of the contoso.com domain:
Get-Mailbox -OrganizationalUnit Contoso.comUsers | Set-Mailbox -SCLQuarantineEnabled $true -SCLQuarantineThreshold 7
You can only configure the SCLJunkThreshold parameter by using the set-OrganizationConfig. To configure anti-spam on multiple mailboxes:
Set-OrganizationConfig -SCLJunkThreshold <Int32>
