I have the domains: globnix.org globnix.net globnix.com The first two are in active use. The third is not used for sending mail and mostly is a placeholder, which makes it rather convenient for various tests, where I need a real registered domain. globnix.com never sends mail. I used to get joe-job backscatter for it. Between DomainKeys and the SPF "v=spf1 -all" I no longer get joe-job backscatter for it. There are many issues with SPF and how it relates to forwarding, but if a domain never sends mail in the first place, then there's no mail to forward and it's safe to publish SPF records for that domain. More, it's polite to publish such an SPF record for that sort of domain, letting others have a lightweight check to reject inbound spam.
