Hm. But this conflicts with my attempt to accept *all* mails directed to
postmaster. (Yes, I could use some variable and delay the rejection, but
this would be ugly.)

Yes, this I understand. But I'd suppose that I know what I'm doing if
I use my own message. And always I can use $acl_verify_message if I
want to expose the real reason.

Somehow I feel the current beheviour not consistent. Is there any
chance to change it?
