Hi,
What is todays most effective combination to filter spam ?
On my old Redhat 3 system I used Sendmail and Spamassasin .. it was
good, but with the current setup we are getting way to much spam.
Looking around I found new players, well some I did not know then and
they are very interesting..
MailScanner .. http://www.mailscanner.info/
Sagator .. http://www.salstar.sk/sagator/
Smf .. http://smfs.sourceforge.net/index.html
dspam .. http://dspam.nuclearelephant.com/index.shtml
I am tempted to go with smfs because it is familiar .. but, mailscanner
seems popular

I use MailScanner but it still uses spamassassin.
I use postfix and greylisting and block e-mails that coming from hosts
that don't resolve by reverse dns or for that matter don't have valid
hostnames. I also use some rbl's.
Those things alone and greylisting knock down most of it so spamassassin
has a much lighter load and MailScanner is awesome.
Same here - I use a 3 phase approach to pre-filtering spam. I use
postfix restrictions (requiring a FQDN helo hostname blocks ~30% on my
server), DNSBL's (zen.spamhaus.org, dnsbl-1.uceprotect.net,
psbl.surriel.com, bl.spamcop.net) and greylisting which in combination
blocks >99% of all spam _before_ it enters the server and needs any
costly post-filtering by SpamAssassin/ClamAV etc. It's an extremely
effective solution for me (YMMV).
