Hi,

SpamAssasin seems to block only 50% of the spam and we just cannot set it to be more efficient. Here is a detail of our setup :

-DNS Blackhole list server :

sbl.spamhaus.org
zen.spamhaus.org
dnsbl.ahbl.org
dnsbl.njabl.org
dnsbl.sorbs.net
sorbs.dnsbl.net.au
blackholes.five-ten-sg.com
cblplus.anti-spam.org.cn
cblless.anti-spam.org.cn


-The "Hit required for spam" is set to 3.
-The DNS service on the server is active but DNS are switched off on domains.

Now here is a few questions :

1. Is it better to set the hit level to 7 or 3 ?

2. The "Black list" under server mail setting is empty. Is it normal ?

3. How can we make sure the transfer with the DNSBL is effective and working fine ?

Thank you for your time,

Patrick Auger
 
Some of those blacklists you're using block legitimate traffic quite frequently - they're not intended to be used publicly.

DO NOT reduce the hit ratio to 3! You'll regret it, as a lot of your legitimate email will start getting flagged as spam, and if any of your users have training turned on, this will effectively screw up their ham/spam ratios by tuning the ham as spam.
