Correct. The appliances tend to be hardened linux boxes, which should have close to zero (nothing is every absolutely zero) downtime, when compared to a windows box I may need to reboot once a week for hotfixes. I'm willing to pay the cost premium to go with a dedicated appliance because of that. ________________________________ From: John T (Lists) [mailto:johnlist@xxxxxxxxxxxxxxxxxxx] Sent: Thursday, January 05, 2006 1:59 PM To: [ExchangeList] Subject: [exchangelist] RE: Spam and A/V appliances. http://www.MSExchange.org/ FYI, all solutions are software based. It is just that some of them come completely packaged into a self contained device. As such, those self contained devices tend to cost more in terms of dollars but less in terms of labor hours.

I'm looking for input on an SMTP e-mail appliances for spam/content filtering and antivirus. I prefer an appliance over software I run on a server, but I'll also accept input for software based products. My exchange front end does nothing but SMTP transport work, and A/V scanning. It has no stores on it. My current spam product runs on the back end servers, because it uses SMTP Event Sink to pick off spam. This means I have to let spam come to the back end server, causes unnecessary load. I want something to put all the way in front to reduce these loads. Two of the popular names in appliances are Ironmail and Barracuda, so I'm obviously interested in those. I'm also looking at St. Bernanrds ePrism, as we have their iPrism already. One of my absolute requirements is how spam is managed. I must have ability for end users to manage their spam and it's settings. In conjunction with global black/white lists Users must have the ability to maintain their own (through web interface, directly in outlook, whatever). The user must be able to view the items in their quarantine. The key to his is the USER has some control. I cannot utilize a device where an admin has to go digging through quarantines for legit mail, or where an admin has to approve a mail from being released from the quarantine. Beyond that, I'm somewhat flexible. I'll continue to use my Exchange front end A/V, but I want some decent A/V functionality in the appliance to reduce some scan load. Based on this, can those of you who have used any of the boxes I've mentioned, and others, provide input on if they would meet my requirements, and what your experiences have been. ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp ------------------------------------------------------ Visit TechGenix.com for more information about our other sites: http://www.techgenix.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: johnlist@xxxxxxxxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to info@xxxxxxxxxxxxxx ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp ------------------------------------------------------ Visit TechGenix.com for more information about our other sites: http://www.techgenix.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: emann@xxxxxxxxxxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to info@xxxxxxxxxxxxxx
