A secure democratic Net is a fundamental right

2008-11-18: Barracuda Owners Take NOTE!

If you're running a Barracuda Spam Firewall go turn the "bounce spam" feature off. Do it right now. All spam is forged. Which means that every spam you bounce will probably hit an innocent third party who had nothing to do with it. This is called "backscatter". It's spam. It's part of the spam problem, not part of the spam solution.

The ability to let a legitimate non-spamming sender know that you blocked their email without causing backscatter has been well known for years. Pressure your vendor to implement it, or move to another vendor, but in the mean time, turn the bounce spam feature off.

The CBL does not deliberately list for backscatter. However, Barracuda-bounced BOTNET spam is generally indistinguishable from being hit by a BOTNET directly, and that is what we list.

So turn it off.
