I see your point, but how many people actually have legit mail servers in the rr.com domain? I haven't seen any yet... same for Verizon and PacBell DSL, etc. Especially for the cable users, I don't think they're "allowed" to run mail servers; all legit mail should be coming from recognizable MX servers set up by RR, etc.Agreed Bruce. Where would one find the *legit e-mail server* info for some of these?
