In short: We had port 25 (SMTP) open for a while, which results in a lot of spam directly sent to mailservers across the globe, which then immediately will get your IP blacklisted at a lot of DNSBLs. Many ISPs don't like their own ranges to contain blacklisted IPs, because that results in lower overall "reputation scores", and sometimes blacklistings are extended to a whole range of IPs, which then affects other customers. -- Moritz Bartl https://www.torservers.net/ _______________________________________________ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays
