Like I said, this is the past 5-10 years. Spoofing mail was one of the first tee-hee hacker wannabee things I did a decade ago. It was drop dead easy then, it is much more difficult now.
If you had an established, implicit relationship with more mainstream mailservers at the time they made up their lists, I would imagine you'd be automatically be on it. Further, presumably these are/were then shared with other trusted parties so as not to create problems for legitimate users. After all, the idea is just to shut out people who try to get around blacklists by not maintaining a stable identity.
In short, Fordy, you're a whitelisted organization, even if you don't know it.
