From 0b4390e7f2322a15f16919425de039d555b3e516 Mon Sep 17 00:00:00 2001

Subject: Make email domain checking optional, as some statusnet installations
 (such as those behind restrictive corporate firewalls, or on home systems on
 restrictive connections) cannot connect to any mail systems, and this check
 will always fail.
