For one of my friend needed to setup a mailserver, he is having a static public IP x.x.x.x without DNS recards, no name resolution, is it possible to create mailserver which is access around the globe..
Certainly, but each domain must have at least two name servers that can resolve names within these domains (for redundancy). Each of the DNS servers must have a static, public IP.
Unless you have some specific need to run your own, it might be better just to use hosted DNS. Many domain registrars run their own name servers that can be used by clients. I also remember zoneedit bweing reasonable back in the day.
It is also popssible to run your own mail server with just a static IP, but I expect such a server to wind up on spam blacklists if there's no DNS name pointint to it. Also, it would be rather inconvenient to have to tell people to send e-mail to user@ip.address.of.server rather than user@some.tld.
