While General email is basically spoiled rotten when it comes to good spam filtering, programs like Microsoft Exchange have to take what they can get. You can probably chalk that up simply to the size of the respective user bases. While everyone with a computer uses email, programs like Microsoft Exchange only have so many users.
Whenever you’re using a program like Exchange and you need to add something to it like a spam filter or some other such update, you’re kind of stuck with very few options out of just scouring the internet from top to bottom in hopes of finding something, and usually downloading the first thing you see.
So in order to give you a little more say in the matter, we’ve gone ahead and listed three of the most popular spam filters for Microsoft Exchange…
EMP
EMP is one of the more powerful applications out there for filtering for your Microsoft Exchange account. Where many spam filters stop at simply blocking known sources of spam and obvious keywords, EMP takes it a step further and blocks cloaked spam.
If you haven’t heard of cloaked spam, it is simply a way of spamming people without spam filters being able to tell its spam by keywords alone. This is accomplished by writing out the obvious words in ways that bots cannot identify, but humans can. So, for example, rather than offering “Free webcam shows!” you would offer “Fr33 W3bcam $hows!” and thus trick the spy filter’s programming into missing the obvious keywords.
EMP, then, is able to spot even disguised spam keywords, and keep them the heck out of your inbox.
SmartPOP
SmartPOP isn’t quite as powerful as EMP, but it is free, so it’s hard to complain too much! SmartPOP is designed to be a simple, easy to use, automatically updating spam filter for your Microsoft Exchange account. While it may be lacking in options, it does get the job done, blocking 98 to 99% of all spam by tracking keywords and known spam sources.
XWall
XWall has about a million different ways to get rid of spam, detecting it by a spam database of known sources and emails, by using keywords, by identifying based on the Bayesian pattern filter, and by sender ID.
A little more powerful than SmartPOP, not quite as powerful as EMP, consider it a great budget priced spam filter for your Exchange account.
