anyone know of any good enterprise spam filters where the user license is less than $1 per user, per month?
Thanks

Symantec's Mail Security for Exchange works well.
Also we use Sunbelt Software's IHATESPAM. There is a client version for ~$18 a year/user and a server version for a bit more than that.

One of the things we've found is that if you are using an SMTP gateway, SAV for Exchange, etc. your servers still have to handle all that traffic.
We use Postini to filter out junk mail before it gets to our SMTP gateway. It will also bounce any destinations that aren't an actual address (from a harvest or spam attack) before they get to our network.
I'm not sure what we paid for it, but it has gotten rid of the SPAM and works very well in our enterprise.

SpamAssassin is basically the best anti-spam solution on the market, and it's an open source project to boot in case being the best isn't good enough. You'll have to experiment with which lists to use to best suit your needs, of course, but it's quite easy to use, by all accounts.
I haven't personally run SpamAssassin myself, but I've been on the "end user" end of SpamAssassin quite a lot, as well as several other popular alternatives. I see far more problems cropping up in environments using other solutions than SpamAssassin, and everyone I know who has used a number of different solutions always ends up deciding SpamAssassin is the best available.
As for Symantec solutions . . . I wouldn't trust 'em for anything, these days. Symantec products used to be acceptable, but since they've become more and more a market dominance company, and less and less a company devoted to quality software, their "products" have greatly suffered. Aside from that, Symantec has been involved in a number of shady dealings over the last few years, including bidding for contracts to service the People's Republic of China national firewall, and as a result I don't feel particularly induced to support them financially.
Sadly, in terms of direct advice about the comparative technical aspects of various anti-spam solutions, everything I've got to offer is second-hand. I wish I could offer more first-hand experience in the matter.
We're quite pleased with them. We have a Windows XP machine that scans the incoming and outgoing email for both viruses and spam. It catches *most* of the spam. The people in our organization who are still receiving a lot of spam haven't made the connection between their Internet habits and the amount of UCE they get.
We are due for an upgrade in both programs and should see a reduction in spam due to the smarter filtering.

Just kidding.....
We use Barracuda & have been happy with the results.

Hi Greg,
You have a choice to make, most of the suggestions involve you doing alot of management of the software and rules. So the spamassassin idea is good but you'd have to look after it, you could add the spamhaus rbl's and you'd probably be able to deal with the majority of spam traffic without too much trouble. However if you just want the job done shop around for one of the filtering services and keep the traffic off your network. I'd suggest The Email Laundry or if you need to go cheaper go Postini but you will have the usual Google customer service standars then.
