Actually they can get the reject, you can sit 4mn and then send the reject.

Now, I re-read the FAQ you pointed to, and I see what you mean. Instead of
sitting 4mn and sending 45x message, I could:
1 wait 1mn
2 print "450- message is spam, please wait for more output
3 goto 1

That definitely sound like an option I could add.
(I'll have to see how exim and local_scan react to the other side eventually
dropping the connection)
