The local(8) delivery agent always case-folds names to lowercase. This is currently not configurable. Ditto for the virtual(8) daemon. It's easy enough to delete the lowercase() call from local(8), but that would not be a general solution. The pipe(8) delivery agent has configurable case folding, and that code would have to be moved into a Postfix library module, so that it can be used by other Postfix delivery agents. Wietse
