Yes, this is standard practice. The drawback is that you have to
accept and discard all the garbage before issuing the reject. Sure
wish SMTP would allow issuing a reject during data - say right
after the headers. This would be a boon to 2822 based authentication
schemes.
You cannot legally do this as below? (I worked out how to do rejects on
the
data command
itself under exim using acl_check_predata so now I don't have to accept
the entire message.

Help! please someone explain to me what you know at Point A that you don't
know at Point B (other than that the client is willing to go as far as
DATA),
and how that makes any difference as to whether you would accept a bounce ??
!!
The above looks like a recipe to try to detect CBV and break it ??? !!
Point A = it's a valid Callback. (No DATA)
Point B = it's a bounce (as there is DATA) that I did not send as
It is being sent to a non BATV encoded RCPT TO
Thanks
Craig
