Re: Too much spam getting through... Sharing rules or db's?

[Jerry]

Jeff,
I have my mail server rejecting he messages if they are in the following 
RBL's before they even reach SA3.

sbl-xbl.spamhaus.org
bl.spamcop.net
multi.surbl.org
blacklist.spambag.org
These messages are being blocked as they are received by our server.  The 96 
messages that came through are ones that did not get rejected directly from 
our mail server.

I am using Net::DNS (upgraded as of this email).
Thank you

to you mean bl.spamcop.net or sc.surbl.org.  The two are not
the same.
This morning I had 96 spam messages.  77 were detected by SA.
Do you mean an 80% detection rate?  That's not too bad, though
it can be improved.

Basically SURBL's are shared DB's of spam identifying information.  I 
put
them on my 2.6x install with the SpamCop plugin and I don't have to 
worry
about spam anymore.  I can't say it's 100% but I would guess about 98%
effective from the people I have talked to.  This is on a mailserver 
with
about 1000 users and spam filtering on all accounts.

Hi,
We are getting a lot of spam messages coming through with low scores.
Anyone have any special rule sets that would be interested in sharing? 
I
use the rules de jour to update my rules but it doesn't seem to capture
all
the spam.

Also,  Is there like a public shared Bayesian database that can help
improve
the detection of spam messages?
TIA
