Barracuda Blocking Emails

We are a business that uses  Server 2003 and Mail Exchange 2007.  Over the past month or so we have been getting our business emails blocked by Barracuda?  These are emails that have gone to these recipients for years with no problems.  Suddenly we are finding rejections by many of our business partners.  My research show that they may be using a Barracuda appliance?  It seems funny that all these companies suddenly decided to use this exact appliance, if that's what they are doing.  How can I fix this?

Both of the comments I've received point me to the barracuda site.  I have visited there, but to no avail.  Can anyone be of further help?  I am using Symantec Corporate Endpoint Protection which show nothing wrong with my system?

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

What do you mean no avail, have you followed the directions?

When you go to the site, click the Lookup Reputation, then click the requaest removal link, fill out the form and send it to them, that's the only way of getting off the list.

You are on the list..you do have a problem.  As I mentioned above you are also on some other lists and you should look into each to get removedl Also you need to investigate why you are on these lists.  The Barracuda site ( at the top) provides many great suggestions as to reasons why you may have been blacklisted but it is up to you to find out.
