I absolutely love our Barracuda Spam Firewall 300. It is way under 4 grand even with 2 years of support and updates.

You can find out specific information about it and even rwequest an evaluation unit by going to http://www.barracudanetworks.com

It does spam and virus catching via hourly updates and a bayesian database/filter. You train it and it works.

I've worked with the Barracuda solution and it works great. Models from 300 and above in addition to the spam and virus features provides you the capability to reduce directory harvesting attacks (random e-mail address generation) against your internal Email server. One feature of this product is that there is no "per user" license. You just buy the box for your environment dependin gon how many e-mails you expect per day (example) and that's it. Most other products charge you per user which brings the price way up there. There are Outlook plug-ins so you users can send "spam" e-mails that bypassed the barracuda and it will send a copy to Barracuda's SPAM Central for analysis so other companies are protected as well.

I would highly recommend you go this way!

We are currently using McAfee's email gateway. We purchased it when it was called IronMail and was owned by Secure Computing. McAfee just recently acquired Secure Computing. The unit works great and blocks a lot of email spam from getting in.

* Web Filter
* Virus Blocker
* Spam Blocker
* Attack Blocker
* Phish Blocker
* Spyware Blocker
* Protocol Control
* Routing & QoS
* Firewall
* Intrusion Prevention
* OpenVPN
* Reports

and then you can add on purchased items such as:

* Live Support
* eSoft Web Filter
* Kaspersky Virus Blocker
* Commtouch Spam Booster
* WAN Balancer
* WAN Failover
* Policy Manager
* AD Connector
* Remote Access Portal
* PC Remote
* Branding Manager

it is a great product. check it out.

See this previous question for other hosted alternatives - why pay for bandwidth at your network's edge when you can have this done "in the cloud"?
