I agree that we don't want to be nice to spammers. But there is also the issue of being nice in the case of false-positives. The extra traffic shouldn't be that great (the message body and headers are not being transmitted). When a legit user accidentally gets into a black-list their request to get the black-list adjusted can often be processed within the time that their mail server is re-trying the message. > even on my little home system, at the end of an adsl line, i reject nearly > 10,000 spams per day (and climbing all the time). i would expect that to > at least double or triple if i 4xx-ed them rather than 5xx, depending on > how much came from open relays or spamhaus rather than dynamic/DUL. 30,000 rejections per day is only one every three seconds. Not a huge load.
