True, but what do you thing Exim should do about it?
Treat 5xx always as temporary? I doubt that's what you want.
Treat 5xx as temporary whenever the word "quota" appears in the reply
text? This is feasible, but do we really want to start interpreting
reply texts which are explicitely intended to be read by humans (and do
not necessarily contain useful information)? I doubt that, too.
