Not cheap at all, but ModusMail does an outstanding job for us. Rock solid and very effective.

Last time I checked (over a year ago), it was saving us 3-4Mbps of traffic (24x7). I would guess now it's closer to 7-10Mbps of incoming SPAM flow that never makes it to our network. Postini also queues are mail if we ever have a major problem. We had our email server have a controller failure about a year ago... while we were fixing it and brining up a new box (4-5 hours), no email was lost or even bounced because Positni had queued it all up (on 10,000+ email accounts). :) Travis Microserv Scottie Arnett wrote: Agreed! Been using Postfix since I told Postini to take a hike. They both use a modified version of Postfix and related add-ons. You can make a spam machine out of the cheapest hardware now. I have been doing this for over 3 years and have a much better customer satisfaction.

Currently we are looking to replace out Barracuda due to ongoing issues with the box that after several attempts to work with Barracuda can not be resolved. Barracuda is helpful but like to point at other things like DNS and unrelated stuff. In the end they log into the box after wasting time so something to kick the box and we are good for an undetermined amount of time. The Barracuda gives us a few features that we like such as an in house box that we are not paying per email address or domain. Also the per user configurability is great for letting users independently control their white and blacklists. In a nutshell what products should we look at that offer us similar features as the Barracuda box. You can roll your own with Postfix and a few addons. After looking at the configuration options for a lot of the Postfix addons, you come to the realization that with a few hours of work, you can have all of the software tools used by the Barracuda internally, and have root access to the box to fix it yourself when it goes south, instead of waiting on them. You can also throw in things like redundant hard drives, and redundant power. How a company can market a $3k+ device with a single IDE drive in good conscience is beyond me. I can't find the link right now, but there is a package that provides users with an accessible, configurable quarantine, just like the Barracuda. I'll post the link as soon as it turns up. ---------------------------------------------------------------------------- ---- WISPA Wants You!
