Or could we meet user expectations (real users, not geeks), and just interpret * and ? (for example) as being regexp values, as well as letting power users use more complicated regexps?
Essentially the two classes:
Simples: *@mail.ru *@*mail.ru ?????@mail.ru
Power-user: ^.*\+.*?\d{3,}@ \.*j\.*o\.*e\.*b\.*l\.*o\.*w\.*+.*@gmail\.com
and the sort we saw in the threads around bot subscriptions and
regexps on Mailman-user?Off the top of my head, the syntax would define if it's an absolute address (foo@example.com) vs a regexp.
