I got a bounce from AOL with the case folded:

Should I worry about this?  The bounce would have been valid if not case
olded.  Also, when SPF returns 'none', should I
check smaller right hand sides?  E.g. check mx.aol.com, then aol.com 
(which would pass).

As long as you are running at least Mail::SRS version 0.30, then the case
folding is not a problem. You should get a warning in your logfile saying 
that an SRS bounce was received with case folded. There are a large number 
of unit tests for this feature.
