I didn't either; that's why you need to know the RFC by heart.  Seems
a reasonable requirement for participation in a project which chooses
its infrastructure based on email controllability! :-)

Yes, if I were you I'd set it to nil.  Setting it to t makes some
*extremely* rare addresses (eg <"an\ RFC\-legit\ address"@gnu.org>,
and that is *not* a joke, it's the kind of example that ADDRESS-MIME
is intended for) look nicer.  But it probably would do really
confusing things to program strings in unstructured fields (eg, Lisp
regexps in the Subject field), and I think those are much more likely
than mailboxes whose names contain special characters.
