On Dec 6 2012, Joe Abley wrote, in re the SOA.rname field:
It's used for (a) legitimate operational communication with a zone maintainer, and (b) source data for people harvesting addresses in order to send spam. Since the e-mail resulting from (b) greatly outnumbers the e-mail resulting from (a), it's a reasonable assumption on the part of an (a) sender that in most cases the address won't be useful. Correspondingly, it's a reasonable assumption on the part of most zone maintainers that the address doesn't matter, unless you're in the business of collecting spam (or have a really effective way to sift through the spam to find the legitimate mail). But perhaps I'm being over-cynical.
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.
