• Personalizing Your Spam Quarantine Filters

You can create safelists to ensure that messages from specified senders are never treated as spam, and you can use blocklists to ensure that messages from specified senders are always treated as spam.

For example, you might receive unwanted email from a mailing list. You can add this sender to your blocklist to prevent email messages from the sender from being delivered.

On the other hand, you might find that email messages from a legitimate sender, that should not be treated as spam, are sent to the Suffolk University Spam Quarantine. To prevent mail from that sender from being quarantined, you can add the sender to your safelist.

Accessing Safelists and Blocklists

To access safelists and blocklists, click on the link in your notification email.

Adding Entries to Safelists and Blocklists

Entries can be added to safelists and blocklists using these formats:

  • user@domain.com
  • server.domain.com
  • domain.com

You can't add a sender or domain to both your safelist and your blocklist at the same time. However, if you add a domain to a safelist and a user in that domain to the blocklist (or vice versa), the IronPort appliance applies both rules. For example, if you add example.com to the safelist, and add george@example.com to the blocklist, the Suffolk University Spam Quarantine delivers all mail from example.com without scanning for spam, but it treats mail from george@example.com as spam.

You can't allow or block a range of subdomains using this syntax: .domain.com. You can, however, explicitly block a specific domain using this syntax: server.domain.com.
