spam howto ... gazillion options ...
http://Linux-Sec.net/Mail/AntiSpam
what is the critiria...
- no false positive allowed ?? in which case, "guessing"
if it is a filter based on scores probably will not work
- some spam filters work better for say nigerian spam and porno
spam but will bomb on say insurance spam and medical spam
- what is your definition of spam ... which will depend
on if its a single user or corp mail server where catalogues
from dell is spam to you but not spam to purchasing@corp.com
- who are you sending/receiving emails from will also dictate
which spam filter you will need to be using
- use different accounts for different purposes which will
eliminate more than 1/2 or all of your spams on the other accts
( it's easier to deal with spam on one acct than on all accts )
simple solution ...
- use the mta's built in antispam provisions ...
( a couple minuts to tweek/enable it ..
- look at the examples ... ( from google/yahoo )
- this can get rid of 90% - 99% of your spams
when you configured the built in filters properly
which is non-trivial for your environment
messy solutions
- use any random spam filters from random.xyz.com
- take your time to figure things out to see how it works
- for the amt of time spent, its NOT worth the extra
5% or so of additional antispam filter it added
vs the generic spam filters that is a matter of minutes
to configure
let-them-do-it-for-me
- you get what you let them do or not do
- you're stuck with their filters
- there is no simple answer for "the spam solution" since it will
be different for everybody
- for me, one false positive ( a real email flagged as spam ) is
completely unacceptable on work accounts
