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 Cisco IronPort 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.

End users can also add senders to the safelist if the message has been sent to the Cisco IronPort Spam
Quarantine. If the message from a particular sender is held in the Cisco IronPort 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.
