Or if they're doing something like Signed Envalope Sender. In that case
they may only accept bounces from envalope sender addresses that have
actually sent mail.
Personally, on some of my domains I reject mail from <> to several addresses
that never send mail, including postmaster. Postmaster is just an alias to
another account, so I never send mail with postmaster as the return address.
Why should I accept bounces to it?
