This is actually not just a 'domainer' issue.
My understanding is that it's an ICANN requirement that the email on the whois gets to the domain owner. So even if it's using an obfuscated email (such as the email address being obfuscated in the whois record), an email sent to that email address MUST be delivered to the domain owner. The registrar cannot block it or send it anywhere else--they have to send it or forward it to the domain owner.
There are a lot of reasons someone may need to contact the real domain owner of a domain, not just because someone wants to buy the domain from them.
Absolutely agreed. And, for the "spam email filtering option," it's concerning whether those agreeing to it understand fully the implications of such a setting.
What puzzles me as well is how it is justified to have first class email also blocked? Aren't there laws against that in the U.S.? If someone has not
explicitly consented to this, perhaps that needs to be promptly changed.
This potentially a very important privacy issue for a company. A business may have multiple domain names, some of which only are currently being used. Do they really want a third party potentially intercepting their first class mail. The term in their GD agreement is (bold emphasis added)
You agree DBP will review and forward communications addressed to Your domain name that are received via email, certified or traceable courier mail (such as UPS, FedEx, or DHL), or first class U.S. postal mail.
Does any business readily agree to have a third party opening mail and package deliveries intended for that actual company? Isn't that a potentially significant security concern? Does the term "review" include actual inspection of the contents of the packages and letters? If so, there would be some very real privacy concerns here.
