We are seing a LOT of valid rejected emails being blocked by the and RBL blacklists. It appears that the owners of these lists are blocking all IPs even if they are valid.

We strongly recommend admins to remove any entries referencing any of the domains * from the MAPS RBL servers in SpamFilter's blacklist settings.

I have instead of, which entry is valid or better? Perhaps we could get a current list of the recommended providers from LogStat, there seems to have been some drifting of the list over the various versions.

Read - this is a combination of SBL, XBL, PBL lists. If you are using the ZEN list, you do not need to also use the other lists individually.

Is that correct?  You are using spamhaus as a SURBL filter?  I did not know that was an option for Spamhaus.

Yes Dan.  At least from what I understand.
Check out this page: -
"Not just for connection queries...

In addition to checking the IPs of the connecting servers against the SBL, you can significantly boost your spam catch rate by also scanning the email body of any mails that get past SBL/XBL looking for host names of URLs (web sites) advertised in spams, and checking the IPs of those hosts, and their names servers, against the SBL. This is because the SBL lists the IPs of spammers' websites in addition to their mail servers."

The owners of the domains (or the DNS for that domain) decided to output the response "" to all DNS queries made for *any* name in their DNS space. When it comes to RBL blacklists, the 127.0.0.nnn response is used to indicate that an IP is listed in the blacklist. This thus caused every single IP on the internet to be reported as being blacklisted.
