Chapter 7 Managing the Spam Quarantine
Accessing Safelists and Blocklists
To access safelists and blocklists, end users whose accounts are authenticated using LDAP or mailbox
authentication (IMAP or POP) must log in to their accounts on the Spam Quarantine. The end users must
log in to their accounts even if they are accustomed to accessing messages through a spam notification
(which typically does not require LDAP or mailbox authentication). If the end user authentication is set
to None, end users do not need to log in to their accounts to access safelist/blocklist settings.

Adding Entries to Safelists and Blocklists
Entries (including those using IPv6 addresses) can be added to safelists and blocklists using the
following formats:
following formats:
•
user@domain.com
user@[203.0.113.15]
user@[ipv6:2001:db8:80:1::5]
•
server.domain.com
•
domain.com
[203.0.113.15]
[ipv6:2001:db8:80:1::5]
End users cannot add a sender or domain to both their safelist and their blocklist at the same time.
However, if they add a domain to a safelist and a user in that domain to the blocklist (or vice versa), the
appliance applies both rules. For example, if the end user adds example.com to the safelist, and adds
george@example.com to the blocklist, the appliance delivers all mail from example.com without
scanning for spam, but it treats mail from george@example.com as spam.

End users cannot allow or block a range of subdomains using the following syntax: .domain.com.
However, an end user can explicitly block a specific domain using the following syntax:
server.domain.com.

Working with Safelists
End users can add senders to safelists in two ways. From the Spam Quarantine, they can manually add
a sender to the safelist by clicking the Options menu in the upper-right corner of the GUI and then
selecting Safelist.

Add an email address or domain to the list, and click Add to List.
End users can also add senders to the safelist if the message has been sent to the Spam Quarantine. If the
message from a particular sender is held in the Spam Quarantine, the end user can select the check box
next to the message, and 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.

Note
End users can also use the spam notification message to release messages. Click the Not Spam link to
release a particular message. End users also have the option to add senders to their safelists.
