Thanks for the heads up, David.

Regarding RHSBLs, here's what wikipedia says about them:
URI DNSBLs are often confused with RHSBLs (Right Hand Side BLs). But 
they are different. A URI DNSBL lists domain names and IPs found in the 
body of the message. An RHSBL lists the domain names used in the "from" 
or "reply-to" e-mail address. RHSBLs are not very effective because most 
spams either use forged "from" addresses or use "from" addresses 
containing popular freemail domain names, such as @gmail.com, 
@yahoo.com, or @hotmail.com addresses. In contrast to marginally 
effective and not-often-used RHSBLs, URI DNSBLs are very effective and 
are used by the majority of spam filters.

Due to their relative ineffectiveness, I don't use RHSBLs at all, and 
recommend the same.
