I understood the problem so:

If you construct the path in the local file system from the username 
derived from the local part, you need to be prepared to handle different 
case names, hence, use %L modifier or return a new spelling from the auth 
DB.

E.g. recipient addresses: fore.surname at example.com, 
FORE.surname at example.com ...

mail_location = maildir:/var/mail/%u/Maildir
