[Mimedefang] Reject vs. bounce

In filter_relay, filter_sender, and filter_recipient, you can return a
value that tells sendmail to reject the message. This alerts the sender
via DSN without requiring an extra e-mail, and guarantees that the server
that connected to you to send you the e-mail gets the error message.
In filter_begin, filter, and filter_end, you can't return a "reject", but
can only do something like call "action_bounce", which generates a
separate e-mail to a possibly forged source address, and is a bad thing.
Why is this? Has sendmail completely closed the connection by the time
"filter_begin" is called? Would having "delay_checks" set in sendmail.mc
help?
Is there *any* way to do a true SMTP DSN-based reject based on the DATA
portion of the e-mail?
