This is a good idea where a predetermined number of errors in RCPT should warrant the sendmail process to abort and terminate. But on the other side, it'll interrupt normal mail messages delivery, hence, causing lots of retries. Default of 3-5 days. I'd suggest to add some intended delays, for instance: when there's a RCPT error, the attacked sendmail daemon will delay say 30 seconds, before it accepts another RCPT TO or other command. Of course eventually the sendmail will time out and drop the connections when necessary. --Joseph
