Subject: Re: Postfix converting ${EXTENSION} to lower case!

Don't use mixed-case mailbox names.

The Postfix local delivery agent translates recipients to lowercase.
This is because people do not remember case when they type in an
email address, and because a lot of mail software does not preserve
case either.

If Postfix were to preserve case, you'd have to be prepared to
receive mail for every possible combination of upper and lower
case, which is painful.
