Spam Management

When an email comes in, the sender of the email is checked against the various allowed and blocked lists , starting with the corporate list, then the recipient’s list.

If a specific sender is on the corporate blocked list but that same sender is on a user’s allowed list, the message is blocked, as the corporate settings have a higher priority than a user’s.More detailed lists take precedence over the more general lists.

EXAMPLE: if a message is received from aname@domain.com and your organization’s Blocked list includes domain.com but a user’s Allowed list contains the specific email addressaname@domain.com, the message is not blocked because the sender’s full address is in an Allowed list.

Use Manage | Security Services | Anti-Spam | Spam Management to select options for dealing with Definite Spam and Likely Spam. The default setting for Definite Spam and Likely Spam is to quarantine the message in the user’s Junk Box.

Choose one of the following responses for messages marked as Definite Spam and Likely Spam:

Response	Effect
No Action	No action is taken for messages.
Permanently Delete	The email message is permanently deleted. CAUTION: If you select this option, your organization risks losing wanted email. Deleted email cannot be retrieved.
Reject with SMTP error code 550	The message is rejected and responds with a 550 error code, which indicates the user’s mailbox was unavailable (for example, not found or rejected for policy reasons).
Store in Junk Box (recommended for most configurations)	The email message is stored in the Junk Box. It can be unjunked by users and administrators with appropriate permissions. This option is the recommended setting.
Send To	Forward the email message for review to the specified email address. For example, you could Send to postmaster.”
Tag With	The email is tagged with a term in the subject line, for example [SPAM]. Selecting this option allows the user to have control of the email and can junk it if it is unwanted.
Add X-Header	This option adds an X-Header to the email with the key and value specified to the email message. The first text field defines the X-Header. The second text field is the value of the X-Header. For example, a header of type X-EMSJudgedThisEmail with value DefiniteSpam results in the email header as: X-EMSJudgedThisEmail:DefiniteSpam.

Select the Accept Automated Allowed List check box to allow automated lists that are created by User Profiles to prevent spam.

With this feature enabled, User Profiles analyze the recipients of emails from members of your organization and automatically added them to Allowed Lists. This helps reduce the false positives, which are good email messages judged as junk. This feature can be configured globally, for particular groups, or for specific users. SonicWall recommends enabling this feature.

NOTE: If this check box is unchecked in the Corporate, Group, or User windows, User Profiles have no effect.

Select the Skip spam analysis for internal email check box to exclude internal emails from spam analysis, resulting in a reduced amount of false positives. If you are routing internal mail through the Email Security product, SonicWall recommends that you enable this feature.

Select the Allow users to delete junk email check box to allow users to control the delete button on individual junk boxes.

NOTE: Leave this check box not selected if you have an extended away/out of the office message turned on so that your auto-reply does not automatically place all recipients on your Allowed list.

Click Apply Changes to save; selecting Revert allows you to fall back to the prior settings.

NOTE: If the navigation or the screenshot looks different from the one mentioned above , you may be in an older firmware version and would require a firmware upgrade. Please refer the link below to upgrade the firmware to latest version.
