For some unfathomable reason, Phabricator is sending me notifications at my old e-mail. There is no e-mail stored in my Profile or Settings (that I can find), and the global e-mail is correct. Why is Phabricator using an outdated e-mail?

Usually your e-mail address is stored in Phabricator; see https://phabricator.wikimedia.org/settings/panel/email/ . Does that help?
Indeed it does. I was overlooking the left-hand panel when looking at my Settings. Embarrassing. All is well now. :-)
