I own a number of domains. One of these domains I use for my primary email address. Is it stupid to use that primary email address as the email address for the owner of that domain? eg, using [email protected] for the owner of example.com. Do I need to maintain a second email address just for this purpose?
In case I need to explain why it's stupid: I recently transferred a domain between registrars and lost control of it for three days, during which the DNS wasn't resolving. If this had been my primary email domain I wouldn't have been able to receive emails sent to the owner of that domain and it would have been harder to prove that I was the owner.
