OK.  I read these differently.  The standard is that the local part _IS_
case sensitive, but the practical implications are not nice (especially
at delivery time, as you noted).  So, the later RFC recommends delivery
behaviour which ignores part of what the earlier standard specified.

Most of us probably follow the latter advice, yet the standard still
honours case.  And just as well, for the sake of those few masochists
out there who actually implement case-sensitive email accounts.

Anyway - your original question has been answered, and Courier does
default to case-sensitive, while providing for that to be disabled.

So long,
Patrick.
