I think we may say that, for any practical concern, tracking IP addresses won't have clear advantages over tracking registered domain names. Rick's very detailed list provides many good hints. However, sooner or later somebody should state some clear instructions for running an MTA. I mean something that a company, an association, or even a household can easily set up and maintain, rather than an art/craft requiring arcane esoteric skills. In particular, tracking registered domain names allows to keep non-DNS settings unchanged through a change of connection provider(s), which seems to me a worthwhile simplification.
