At work we have been evaluating the RazorGate project. This product is a Anti-Spam and Anti-Virus mail filter appliance product.
Administration: The web interface is quite bleak. Very light weight and not incredibly user friendly. There isn't a whole lot of configuration to the product, you enable the various features and not much else. It does keep extensive logs on the messages that pass through the device. The server supports SSL. Also it has a telnet interface which I have not used extensivly but can do real-time displays if mail traffic.
Anti-Spam: One if the first things I noticed is right on the anti-spam it says that it is based on SpamAssassin. The rules it uses are based off a service that Mirapoint provides. They are very strict rules. From what i've found if the message has HTML is will get makes pretty highly. They use a 0-300 score level It does White and Black listing. and use RBL lists.
Anti-Virus: It is based off of Sophos for antivirus. This seems to work pretty well. her have gotten out fair share of the common virii out there and they have been caught. I have not seen any on the antivirus on the internal mail server.
Untested Features: This box will also act as a basic mail server handling POP, IMAP, and Webmail. Mailhurdle, they advertise this anti-spam feature very highly but i have not tested it out.
Over all this is a pretty effective appliance. i would recomend it but you will as with any anti-spam solution have to play with the filter to get the right ballance of score for your mail traffic. We have had to make heavy use of the White list.
