There is no security bug. milesstandish@gmail.com and miles.standish@gmail.com are the same account. To prove this, log out of the former, and into the latter using the same password. You will see all the same emails. Sign out and in again with m.i.l.e.s.s.t.a.n.d.i.s.h, using the same password. Those emails you are receiving in error are probably for someone like miles.p.standish, who forgot his middle initial when sharing his address.
