A New Type Of Realtime Blocklist: The SURBL

Posted by timothy on Monday April 12, @05:02PM from the chicken-egg-spam dept.

Glamdrlng writes "The SURBL, or "Spam URI Realtime Blocklist", represents a nexus of RBL's and content filtering that may bring us one step closer to a spam magic bullet. While traditional RBL's perform a DNS lookup on the connecting mail server, SURBL's take this a step further by parsing the text of the email looking for URI's and doing a lookup on those web servers. They also prevent "joe jobs" by maintaining a whitelist of legitimate web servers whose domain names may show up in spam messages, e.g. EBay, Paypal, Microsoft, etc. The only requirement to implement the SURBL is a plugin on your MTA such as spamassassin that can parse the body of each email. While there is no MTA that directly supports SURBL's without a plugin, the author hints at one being in development."
