 Hi all,
 I wanted spam filtering suggestions for a friend who's server is running
 qmail and spamassasin. They are also using spamhaus for RBL checks. This
 is still leading to a lot of junk email and i wanted to know what are
 you all using to tackle spam. He would be interested in a free or paid
 solution that can filter as much as possible.
 thanks.

Have you considered grey listing ? That will drop anywhere from between 
85 - 88 % of spam at this time( numbers from an active metric done on a 
moderately busy domain a few weeks back) . The number will keep reducing 
over the next few years, but expect it to stay  70% for atleast another 
year +

I agree. Here are some similar stats from the greylisting daemon running
on a server for the last year and half:

List statistics since Fri May 20 17:55:24 2005 (572 days and 2 hours ago)

Of 263499 items that were initially greylisted:
 -  52516 ( 19.9%) became whitelisted
 - 210983 ( 80.1%) expired from the greylist

And my criteria of greylisting is:
1. greylist all mails which come from 
2. greylist all mails which come to specific domains.


the only issue I have seen in using greylisting is customers not
understanding why mails from customers are getting delayed or some
braindead mailservers which bounce messages after seeing even a message
deferred. Please try later status.
