We use two St. Bernard's ePrism1000 appliances in a cluster mode. It can also handle AV. It works pretty ok. Once in a while we get spam, but it's very minimal. Users can also have some control. Suspect spam emails end up in their Junk Folder.
The reasons for the selection about 2 years ago were: * A self-contained unit with web interface that can be directly attached to the network * Dependant only on an external MX record for operability * Built-in redundancy either through hardware or software * No impact on the ability to send/receive email in the event of failure * Can utilize real time black hole lists and a distributed checksum clearing house * Can utilize Bayesian filtering, malformed message protection, heuristic message scanning, configurable white lists and black lists, and reverse DNS lookup * Can provide another layer of defense against email borne viruses, with ability to schedule updates for virus definitions via the web * Contains user controlled lists and quarantines, which can be configured and managed by the end user, without needing third party client side software. . Can be used to generate usage reports for incoming emails, and Spam related messages, as well as for denied incoming messages, including the policy that prohibited the inbound message. . Comparable or equal cost to other solutions such as: Iron Mail, McAfee SpamKiller, Tumbleweed, & Barracuda. Overall, I think you need to make a decision based on first identifying what's important to your company (system requirements), risks involved, and how much it'll cost to implement and manage the solution (software, hardware, time, and human resources).

We need something that is mostly hands-off as we have limited staff. I am trying to compile a list of possible alternatives and was hoping you kind folks might be willing to share your suggestions or experiences. It's quite all right with me if you prefer to respond off list. Thanks in advance!
