There's a difference between aliasing of "john.doe" to "johndoe" and being able to take an account "johndoe" and work around broken sites that don't accept + in an email address by encoding your address as "j.oh.ndo.e" and still have it work. I didn't claim Google invented it. I claimed that it was unusual at the time. I stand by my assertion that canonicalising away all dots was unusual at the time. Please criticise what I actually write. There's usually plenty to criticise in just that. :) -PHil _______________________________________________ dns-operations mailing list dns-operations@lists.dns-oarc.net https://lists.dns-oarc.net/mailman/listinfo/dns-operations dns-jobs mailing list https://lists.dns-oarc.net/mailman/listinfo/dns-jobs
