malwaredomains.schulte.org

This is a DNS-based RHSBL list, compiled from a number of sources.
You can use this list with any service that understands RHSBL logic.

For example, I use Postfix as my MTA, so my rules look like this:
        reject_rhsbl_client malwaredomains.schulte.org,
        reject_rhsbl_reverse_client malwaredomains.schulte.org,
        reject_rhsbl_helo malwaredomains.schulte.org,
        reject_rhsbl_sender malwaredomains.schulte.org,
Customize to your own needs.

I don't have wildcard records to match subdomains. If you want that
then your best bet is to build a policy server that uses this as
a data source.

Note: I don't maintain the domains listed here, so I can't help you
de-list a domain. I recommend using this site for researching your
domain or IP address's reputation: http://multirbl.valli.org/
