Just to put this into perspective: I don't think the Hetzner situation is that dire overall: I just checked the Talos/SenderBase scoring for some Hetzner nets and they were not so bad. For example the top 50 ips from 78.47.0.0/16 (by email volume) there were 34 IPs with "good" reputation and 7 with "bad" reputation. I am sure my customers would not tolerate blocking networks with similar statistics. Personally if I expect sophisticated measures from dc providers (SMTP proxies, even forcibly terminating TLS connections) I also try to do something more sophisticated when it comes to classifying received messages. (E.g. we are building our own internal IP reputation so initially unknown IPs might get a bad rating from the network but these messages still have a chance and over time the IP might get its own reputation so it will be unaffected from the general network storage.) Anyhow I'll stop here as I feel I'm off-topic now :-) regards Felix _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
