A new feature has been added to the spam protection system that helps to determine what is a spam or junk email. This feature, a new Realtime Blackhole List (RBL) named SURBL, analyzes the content of each email to see if any of the domains or URL’s listed in the email are known spammer websites. If they are, the email is more likely to be spam, and is weighted more towards spam for the final determination by the software.

This new RBL is revolutionary in the fight against spam, as it does not care where the email originates from (as most spammers forge the From: field and use hijacked servers and computers to send out their junk mail), but rather sees what URL’s and domains the email is trying to get people to go to or show images from in the body of the message. This is very effective, as spammers must use a website to display their images or for people to go to in order to purchase an item. The new RBL catches these websites, and can greatly help classify an email as spam.

The new feature is already in the software, so no changes are needed in your spam settings. As long as you have the setting turned on for checking the Realtime Black Lists, then this new option will be automatically used for each incoming email.
