What is an RBL and how did I get on it?

RBL stands for Real-Time Blackhole List. An RBL list is a dynamic list of IP addresses identified as active spammers. RBLs are also called DNSBLs and wikipedia has a really detailed article on them, if you'd like to learn more.

We also have a great Community Site post on blacklists.
