I got a 450 greylist on mx2.hub.org but a hard error on mx1.hub.org.
Which one did you try?  Note that there's also maia-1.hub.org or
something like that.  I'm not sure what's each server; weird crap from
hub.org I guess.  I tried an address without the =foo=bar.baz part too;
I think Majordomo uses different patterns depending on whether the
sender is subscribed, or something like that; but they should both work.
