Server side multi user spam protection
 

I am looking for a program that will protect multiple mail boxes for multiple users.

I want the software to do this on the server so I don't even see the mail when I download it in outlook.

Does anybody have any software in mind that can do this for me?

Many thanks in advance. |thumb

Depends on your skill level.

Greylisting (http://projects.puremagic.com/greylisting/) -- this probably knocks out 80% of the spam right off the bat.

I'm not a fan of SpamAssassin, but, many people like it. A quick procmail or mailfilter recipe can get rid of tagged spam. Beware, dealing in the adult industry, you'll likely delete valid messages due to their pre-concieved notion that porn = spam.

My personal favorite is DSpam (http://nuclearelephant.com/projects/dspam/) which is statistical and trainable. There is a quarantine section so that you can see the spams that were tagged and retrain if it has a false positive.

There is also CRM114 which is again statistical.

Another thread that discussed this earlier this year:

Thank you very much, I like the sound of the trainable one. Checking nuclearelephant now. :)

Why not just setup something like vanquish or spamarrest - I use vanquish myself and get rid of 99% spam.

NB! you can only have 5 users on one account though (vanquish)
