Chapter 27 Quarantines

Using Safelists and Blocklists to Control Email Delivery Based on Sender

Adding the Sender of a Quarantined Message to the Safelist

End users can add senders to the safelist if the message has been sent to the end user quarantine.

Procedure

Step 1

From the End-User Quarantine, select the checkbox next to message.

Step 2

Choose “Release and Add to Safelist” from the drop-down menu.

The envelope sender and the from header for the specified mail are both added to the safelist, and the
released messages proceed directly to the destination queue, skipping any further work queue processing
in the email pipeline.

Adding Senders to the Safelist Without a Quarantined Message

Procedure

Step 1

From the Spam Quarantine page, select the Options drop-down menu in the upper righthand corner.

Step 2

Choose Safelist.

Step 3

From the Safelist dialog box, enter the email address or domain. You can enter multiple domains and
email addresses, separated by commas.

Step 4

Click Add to List.

Adding Senders to Blocklists

When the appliance receives mail from the specified email address or domain that matches an entry in
the blocklist, it treats the mail as spam. The mail may be rejected or it may be quarantined, depending
on the safelist/blockist action settings.

Note

Unlike safelist entries, you can only add blocklist entries from the Options menu in the End-User
Quarantine.

Procedure

Step 1

From the End-User Quarantine, select the Options drop-down menu in the upper right-hand corner.

Step 2

Enter the domain or email address you want to blocklist. You can enter multiple domains and email
addresses, separated by commas.

Step 3

Click Add to List.
