What I care about is having my rules work.  What I don't care about is 
if some sender converts my email address to upper case.

The problem:

(1) Some services convert email addresses to all upper case.  They 
shouldn't, of course, because technically the semantics of the 
local-part is entirely up to the receiving domain, which could enforce 
case sensitivity if it chooses.  But the fact remains that I receive 
some email where the address that reached me was converted to all 
uppercase.

(2) MM rules seem to be case-sensitive.

 From my point of view, I want rules to work regardless of case.
