Postfix Cyrus Web cyradm HOWTO

The best method how to prevent SPAM is to handle your e mail address as your best

treasured secret. NEVER put your address in a web form or put it on your website. I

In the beginning of SPAM, filtering for keywords like  viagra  was enough. Todays

SPAM techniques are much more sophisticated. It is a war between users and

spammers. The solution against sophisticated SPAM is even more sophisticated

anti spam software.Todays anti spam software checks e mail for more than just

keywords. They are checking for specific mail header data etc. Also a technique

called bayesian (http://en.wikipedia.org/wiki/Epistemic_probability) filters which

can learn from particular input, distributed checksum networks etc.
