Why take the time just to victim blame? A decade ago, I added some text to our 5xx rejections to try to be helpful. The RFC explicitly guarantees that doing so will have no negative effects. Fuck me I guess? The response does *not* say that they're blacklisted. The only reason they won't do the right thing and simply retry is because it saves them money when sending spam. The arguments about scale are smoke and mirrors. Your opinions are yours, but you're defending billionaire spammers who knowingly breaking the rules because the rest of us pay for it. _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
