The problem isn't mail sent to valid addresses, it's mail sent to non-existant ones. Normally they would be rejected by esmtpd, but when you have a .courier-default alias they are accepted.
Solution: remove the .courier-default file. Problem solved.
That's a problem because spammers try to guess addresses, resulting in a lot of mail that gets accepted and then bounced. It'd be better to not accept it in the first place,
If you don't want to accept it in the first place, then don't.
but for my needs, which requires a trivial rewriting of recipient address, I can't see any alternative to a default alias.
There's certaily a better alternative: modify your authentication module to do the necessary writing.
