I know you're on OVH but it's hard to feel bad about this. Morally, the ISP (the owner of the netblock) is responsible for the spam. They have a responsibility to stop it. If they outright refuse to respond to abuse complaints, it's good and correct to punish them for that choice. Practically, whack-a-mole is infeasible. It takes me five to ten minutes to add a blacklist entry: I have to do the WHOIS lookup, PTR lookup, scan the neighborhood, see if that block is part of a larger block, document the spam, add the blacklist entry, write a commit message, push to the repo, and then push the configuration change live. It takes OVH less time than that to send me spam from a new IP address. There's an obvious solution to that problem and it isn't me doing their job for free, twenty four hours a day, for the rest of my life. _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
