For members of a group, Stalwart 1.0 lists the group's identity (for example `team@example.org`) before the user's own. The identity sort put the identity matching the login first, but compared addresses case-sensitively, so a login typed as `UserA@Example.org` defaulted to the group address. The identity manager kept its own copy of the same sort. Both now use one sort that compares addresses regardless of case, and with an internationalized domain in either its Unicode or its `xn--` form.
