Editor's Note: This is something I found on the web ( http://www.nwfusion.com/news/2002/0909spam.html ) that I thought you would like to know about.
Network executives should follow a few general deployment guidelines to reduce the amount of legitimate e-mail that spam filters might block.
Run the software in a monitoring mode first to help you gauge what is being blocked before going live with end users.
Start off with a conservative attitude toward blocking, which will let a lot of spam escape the filter but nearly eliminate false positives, and work your way up to an acceptable balance.
Use a combination of filtering techniques, such as keywords, domain and IP blocking, blacklists, whitelists or collection accounts. Look for software with more sophisticated filtering methods such as heuristics.
Quarantine blocked mail and give users the option to see their mail that has been filtered before it is deleted.
