[dns-operations] DNS and Email

[Feng He]

I found a interesting case that, most people on DNS lists have been 
using the email accounts from their own domains.
But people on many other lists use the email from general providers like 
Gmail, yahoo etc.
So that indicates DNS operators most likely play well on their own 
domains than choosing a general email account.

And I have a question that, what is the good username for showing in the 
whois info for domain contact email?
admin at domain.com
dnsadmin at domain.com
hostmaster at domain.com
...
?

Regards.
