Does anyone know of good Block List for emails that are free? I am trying
to setup Exch2003 to block spam as much as possible.

Thanks

I found SORBS but am not sure what the proper settings are for this.

Here is some of what they list. Do I configure this in the Ex2003 "Message
Delivery" or DNS

I would think Exchange, but I am not sure. If I type the addresses below I
get an actual webpage, not a listed of blocked sites. How does this work.

dnsbl.sorbs.net - Aggregate zone (contains all the following DNS zones)
http.dnsbl.sorbs.net - List of Open HTTP Proxy Servers.
socks.dnsbl.sorbs.net - List of Open SOCKS Proxy Servers.

Any help would be appreciated?!

Thanks again

Hi,
I am pasting some free ones below. Don't know which ones are best, but in our company we use
SpamCop.Net and ORDB.

One suggestion, if you are trying to eliminate spam, don't rely on IP filtering alone.
Spammers have gotten very smart lately - they hardly use one IP address. Therefore,
in my opinion RBL alone is not enough. We use Spam Marshall in our company and it does
a nice job of filtering.

Thanks for the info

When I type in the address (relays.visi.com), I would put this in the
Connection Filter of the Properties page of Message Delivery. Correct?

Some of SORBS is okay to use, but I wouldn't trust their "spam" list.

The xbl/sbl list at spamhaus.org is a good one, as is njabl.org
