Mac Mail 5.3 & RT threading

We are using RT 4.0.2, and are having problems with messages in recent
Mac Mail (5.3) not threading properly. I modified our comment
template to put “Re:” at the beginning of the subject, before the
SubjectTag, and that helped, but has not entirely fixed the problem.

Is anyone else dealing with this, or have helpful suggestions about
how to fix threading?

If you can find information on how threading works in the app then we can
help. Otherwise
it’s guessing. RT sets required headers to setup threading, but some MUAs
use alternative
algorithms and very sensitive to subject.
