[rt-users] Failed to load valid user when Everyone has the right to CreateTicket

[Fran Fabrizio]

Occasionally, I get a

RT could not load a valid user, and RT's configuration does not allow
for the creation of a new user for this email (user at uab.edu).

even though in this queue, Everyone has the right to CreateTicket.  (There's nothing special about @uab.edu, I just picked that as the latest example - it happens with all sorts of domains) 

Has anyone else seen this?  It's sporadic, once every week or two.  RT 3.6.4
