If you're interested in the details, the canonical sources on all this are a paper by the Messaging Anti-Abuse Working Group, available at http://bit.ly/157FVN and a proposal by the Anti-spam Technical Alliance that you used to be able to get at http://postmaster.aol.com/asta/proposal.html but can't any more.
