Indeed. This second option is what my ISP is planning to do. Except that they don't actually care about customers who need reverse DNS now. But yes, manually adding a PTR is also a very good solution. Especially, because it will be very hard for malware to automate that. Making it hard for malware to send mail from a system with reverse DNS. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
