Every one of us knows how spam impacts us. Every day we either getton of spam - or if we're fairly well protected by spam filters - onlyfew pieces.
Likelarge number of people, I do not use any spam filters. Ah. You think I am insane. But wait. My problem is that I getlot of email from marketing types which I want to receive. Andspam filtering software is not very sensitive to my needs. Even white-listing doesn't always work. So, I prefer to get all that spam and just delete it.
Now this solution can work for me despitetime it takes to delete my daily overdose of spam. However, atenterprise level, it'swhole different story. If you haverelatively large internal network with evenmodest number of email users, you're looking atmajor problem. Andmore users you have,worseproblem is.
Sure, you can put up software onmail server. Works, kind of. But pretty soon you may find you need to upgrademail server. And that's after you already put it onstand-alone machine.
Rather than continuing to buy ever more expensive software to run onmachine that keeps needing to be upgraded, you might want to think aboutdedicated anti spam appliance.
To give you some idea of what's possible let's takelook at Barracuda Networks dedicated anti spam appliance. All you need to do is put this baby in front of your mail server. I say baby, advisedly because this one will learn by doing and by training provided by your users.
Dean Drako, CEO of Barracuda Networks said, "Bayesian filtering is still one ofmost accurate defenses against spam. The new plug-ins allow users to directly trainBayesian filter, makingBarracuda Spam Firewall even more accurate based onusers individual email preferences. Viruses and other threats can infectnetwork quickly if they are not stopped atnetwork edge. With Intent Analysis our customers haveadvantage over these threats becauseBarracuda Spam Firewall is able to block them real time. Consequently we have consistently beenfirst responder when some ofmost malicious virus attacks have hit, saving our customers from potentially devastating damage to their networks."
This is one beautiful little machine. A Barracuda Spam Firewall can support from one,zerozerozero to threezero,zerozerozero active users. It can usually be installed in less than five minutes and receives automatic hourly updates for new forms of spam and viruses. It hasonezero layer defense system beyonduse of open source anti spam and anti virus solutions: denial of service and security protection, IP block list, rate control, virus check with archive decompression, proprietary virus check, user specified rules, spam fingerprint check, Intent Analysis, spam rule-based scoring, and Bayesian analysis. Plus it also does both inbound and outbound email filtering withinclusion of sophisticated outbound email filtering techniques (just in case you've gotspam zombie on board or somebody's gotinfected PC).
However, it is not exactly cheap. Still, when you considertime, bandwidth, user frustration and potential hardware upgrade costs,price may looklot more reasonable. You can check it out at http://www.barracudanetworks.com/
If you are inmarket foranti-spam appliance,Barracuda Spam Firewall is not your only choice. The impact of spam on internet businesses - even those who primarily use it for just email - is so great thatsimple search for "anti spam appliance" will find younumber of alternatives to examine. Even McAfee is getting intoanti spam hardware game.
I am hoping that it will not be too long before I can pick upBayesian multi-level anti spam, anti virus firewall appliance for my home PC that keeps me safe and cuts my need to delete without deep-sixingemail I want or costing me more than I can afford. I suspect it's onway.
