It does, but AFAIK, it is a royal pain to tell it to lowercase everything
using rewrites (rewrites in postfix are table based).  Lots of overhead...

I foresee trouble with postfix in that area, so I will be enhancing that
patch shortly.  It is MTA-agnostic, and it might help people with other
MTAs in the future anyway.

Mind you, I plan to request postfix lmtp to be configurable to lowercase
everything _as well_, but I must locate and read the thread that caused
people to switch that off in the first place...
