They also can use SMTP AUTH for what they call Recipient Verification. Barracuda has done some work in the past few years to improve its "out of the box" configuration, but its poor start has permanently tarnished its reputation in the eyes of some in the mail community, especially those who are able to build their own spam filtering solution. As I found in a previous e-mail I wrote in September 2008, Barracuda's next release, as documented in their release notes, will, without asking, turn off all settings that cause backscatter. Customers will have to specifically re-activate those "features" if they want them. The "Send Bounce'' option will be SET TO NO on all systems, regardless of your previous setting. If you wish notifications to go out to any sender whose email was blocked, you can re-enable this option from the "BASIC->Spam Scoring'' page, in the Spam Bounce (NDR) Configuration section.
