If anyone has any actual evidence of SOA data being used for spam I'd love to see it ..

I think you are being over-cynical. Spam is a fact of Internet life, however one advertises contact addresses, and I don't actually see much evidence that spammers collect SOA.rname values rather than picking things out of web pages, mailing list archives, etc. Our main hostmaster address, in the SOA.rname of e.g. "cam.ac.uk" gets lots of spam, but not much more than an alias which was almost certainly picked up from web pages, while an SOA.rname for several other zones[*], which probably appears in no unrestricted web pages, gets almost none. [*] No, of course I'm not going to say which they are here... :-) -- Chris Thompson University of Cambridge Computing Service, Email: [email protected] New Museums Site, Cambridge CB2 3QH, Phone: +44 1223 334715 United Kingdom. _______________________________________________ dns-operations mailing list [email protected] https://lists.dns-oarc.net/mailman/listinfo/dns-operations dns-jobs mailing list https://lists.dns-oarc.net/mailman/listinfo/dns-jobs _______________________________________________ dns-operations mailing list [email protected] https://lists.dns-oarc.net/mailman/listinfo/dns-operations dns-jobs mailing list https://lists.dns-oarc.net/mailman/listinfo/dns-jobs
