Did you register that domain with PP?
That email address shows you own that domain and if it is the same as your PP address that is probably why they have limited it.

Yes, this domain I registried in godaddy at first, use paypal. And the domain whois email is same to the paypal email. I just contacted that third party dns service provider. Seems they has a loop that anyone can add any domain in their account. And if someone else set the DN record with their DNS and forgot to cancel it, then the domain can point to the one who add it later in his account.
I think I know the problem...Any way, thank you to help me out. Although I don't know if I can get my domain and paypal back.
