Proxmox appliance, free for single domain. I use the pro version with about 20 clients, 50+ domains, and maybe 2,000 mailboxes. Runs without a hitch. Requires almost 0 maintenance and is offsite.

Sold it to a couple of small customers with no complaints as of yet. My question is regarding email spam filtering. I know a lot of you VIPRE users perhaps are using Ninja, which I'm assuming is server-based. For years I have been using Katharion, which is similar to Postini as an offsite-based filter. I'm just curious as to what you guys prefer when it comes to these kinds of apps, or if you prefer appliance-based filtering. Thanks, Jay Jay Dale . I.T. Director Xpresstel, Inc . Telecom & I.T.
