Hi, I have been looking for a solution for this for quite a few years. You have either very expensive antispam appliances such as the Ironport or Barracuda, or you can build your own. The issues with your own is that it can take ages to get a quarantine manager up and running. Here are some suggestions of products I have tried: SpamTitan http://www.spamtitan.com - self-contained Vmware appliance built by an Irish company. This is the most user friendly interface but slightly more expensive than Security Gateway etc. Security Gateway from Alt-n http://www.altn.com - cheaper, runs on Windows, has a slightly less user friendly interface, and does some weird things with NDRs. Has a very good spam catch rate when used with the ComTouch engine, and has a lot of new features like DKIM and SRS which are missing from SpamTitan. I am using this currently as you can see from the headers. I would also take a look at Astaro mail security - I have heard good things on it in the past few months. Have you looked at an external antispam solution? Again ranging from very expensive solutions such as MessageLabs, but Google do one now (they purchased Postini), and there are a lot of other companies doing the same thing, some make it their core business and some do it as part of other services. I have heard good things about Webroot/EmailSystems, but there is no prices on the site which always makes me think they are going to be expensive. When I migrated the company to Exchange 2007 a couple of years ago, I chose Mimecast for this task because it clouded the email archiving solution. They don't have the most user friendly web interface, but their antispam/AV features are really solid. Thanks. Andrew. -----Original Message----- From: blind-sysadmins-bounces@lists.hodgsonfamily.org [mailto:blind-sysadmins-bounces@lists.hodgsonfamily.org] On Behalf Of Darragh OHeiligh Sent: 03 March 2011 14:15 To: Blind sysadmins list Subject: [Blind-sysadmins] Anti spam for exahange. Good afternoon, I am looking for an anti-spam product to protect against spam for Exchange 2007. I know Exchange has it's own validation however this is frankly rubbish. I don't mind if I have to build another server for this. It should be able to check against something like trusted source and should allow users to independently unblock spam. Any ideas?
