I just came across an elegant alternative to our Self-Spam Agent (which stops spam sent in your name) in Alan Hardisty’s blog. While Alan’s solution takes at least Exchange 2007 and the Self-Spam agent will support Exchange 2000 and newer + IIS SMTP, it is a beautiful demonstration of what Exchange 2007 can do for you.

The ORF team will make an appearance at the annual Infosecurity exhibition in Brussels at the end of March. The event will be at the Brussels Expo on 24-25 March in Hall 8.

We will be going around the floor all day, so if you want to meet us in person send us an email (orf@vamsoft.com), we will be around on both days.

It has been a while since I last compiled our own ORF statistics using the Reporting Tool and what I am seeing is that SURBLs are taking over DNS Blacklists.

Is it just us, or are SURBLs really taking over? You can check your statistics in the Test / Summary section of any ORF report created with the ORF Reporting Tool.

UPDATE: Actually, there’s an explanation for this. Recently we switched to all-On Arrival filtering on our server and that means SURBLs are tested earlier than DNSBLs (see General Information / Test Order and Priority in the ORF Help), hence the more emphasized role for SURBLs.

That does not change the fact that SURBLs alone do a great job. ORF cleans up the the traffic step by step and 30% of what’s reaching SURBLs is cleaned up by them, leaving behind a much more legitimate traffic for DNSBLs, which cleans up another 8%.
