Setting up a email spam filtering system locally: Anyone have ideas?

Spam email

[gtate]

Anyone got any good ideas for an easy to set up and operate spam filtering system? I find that commercial servers don't generally offer an effective filter, and my clients all complain about the quantities of spam they receive. Further, I don't find that the sort of 'black list' and 'white list' option offered for instance by Norton is any good as it is too time consuming and anyway doesn't work very well.

Hotmail accounts seem to have much better filters, does anyone offer this sort of service?

I've never tried to set up my own system as the multi-stage filtering from several sources seems to do the trick.

Perhaps there are some other folks with some ideas.

Look at Bayesian filters for your local mail. It learns as you go. You tell it what's spam and what's ham and soon it does the filtering for you. It will also pick up on the bad-guy's new methods quickly as well.

For a comprehensive filtering system that will learn more than just spam/ham classification, look at PopFile. If you want spam filtering then SpamBayes is the best. Both are open source.

For years I have been using mailwasher
both free and for a fee version are very fine tools.

Also my emails and most web searches are performed only out of a non networked dedicated machine.
