is that specifically in violation of an internet protocol? I ask as I
similarly reject after DATA when the spam score at DATA is higher
that at RCPT time, this can happen if the spammer has hit many
unknown local users, as each of these will increment the score. I can
then better protect existing users that happen to be in a dictionary
scan run or other multiple recipent spam delivery.
Also, any content based rejection will reject at that stage.
