I have this as my first entry in my RCPT ACL:

#------------------------------------------------------------------------------
# Drop the connection if too many failed recipients.
drop
  condition   = ${if > {${eval:$rcpt_fail_count}}{3}{true}{false}}
  message     = Too many failed recipients - count = $rcpt_fail_count

Thus if there are more than 3 failed recipients given I drop the connection.
If you want to delay too, I think this will work:

#------------------------------------------------------------------------------
# Drop the connection if too many failed recipients.
drop
  condition = ${if > {${eval:$rcpt_fail_count}}{3}{true}{false}}
  delay     = 60s
  message   = Too many failed recipients - count = $rcpt_fail_count

I hope this helps,
