Word list filters don't work.

They don't work well on their own. If you use them along with Blacklist providers and other spam filtering features, they can help a bit. Realistically, though, the word block lists are more meant to manage what type of email can get through. Filtering sexually explicit terms can help keep you from unwittingly storing pornography on your email server, for example. That said, there aren't a lot of pre-defined word lists that are designed for exchange, but if you can find a CSV file with a bunch of words you would like to block, you can script the addition to the lists.

GFI Mail Essentials comes with a list of &quot;bad words&quot; which I have ended up removing about a third of the entries from because they were blocking legitimate email messages. Spammers also know words are blocked and will work around them. <br />
Then there is the Scunthorpe problem. <a href="http://en.wikipedia.org/wiki/Scunthorpe_problem" rel="ugc">http://en.wikipedia.org/wiki/Scunthorpe_problem</a><br />

Thanks, I should probable configure a couple of DNS black and white lists. This seems to be the best way forward?

<div>
That depends if you are happy for an unaccountable third party to decide what email you can and cannot receive. <br />

Hi, Just setting exchange 2010 up. We used to download from a catchall via our isp that used to block most spam. Not our MX records are direct and we are getting quite alot of spam.<br />
<br />
I know exchange 2010 has content filtering which I will be enabling. My question is can someone point me in the direction of a pre-made &quot;Block messages containing these words or phrases&quot; list that I can paste into exchange?.<br />
<br />
Thanks<br />
David,

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.
