Finally figured out why I couldn't get my email verification link from the wiki: the mail server for Pathfinder Wiki is configured incorrectly, and it's being blocked by my mail server. The error is "Sender domain is not found", with the mail originating from firstname.lastname@example.org. And it's appears true - that domain does not exist or resolve, and most mail servers are going to deny that.
Hmm, good catch. That domain name expired last fall, and it seems I forgot to update he mail server config. I think I've done so now. Let me know if you still have issues.
I can confirm the change.
