At a very minimum, you should fully understand the impact of backscatter as well as the extremely viable vector for spamming/spreading malware through the use of forged headers to relay payloads through NDRs/DSNs
why in the world would a reject *before queue* trigger a backscatter or bounce on my side?
the whole purpose is to *not* produce bounces *nor* silent discard - the sending MTA is repsonsible for bounces to *his* users after a reject and a bot just ignores the reject
if you are talk about "have no business running a mailserver" and "you'll do more harm than good" you should know that
