There was two issues above. 1) reject mail being sent to valid usernames
and 2) bounce mail sent to non-valid usernames without accepting the message.
As you note, 1) Is "easy" to patch in. 2) Is non-trivial.

True, but since when has processing be a major issue in a qmail box?
And if the sender is a valid user then qmail will make sure he gets an
error message.

Yes, but this is only going to resolve "1" above. I noted to the thread poster
that he can use procmail to ensure that only his system can email his
database; and Mark pointed out that he can leave the domain out of
rcpthosts which will prevent qmail-smtpd from accepting it from
remote sites. If the domain is his normal one, then it shouldn't be hard to
use Mark's method and make up a dummy domain for which a .qmail-default
can relay the email through to his database.
Why does anyone need a control file for "badmailto" ? Think about it. You
don't need one. Why would you want to list valid users email addresses in
a "badmailto" file? (listing non-valid addresses isn't going to do much,
except saving qmail from having to generate a no such user bounce).
