I have a CentOS 6.3. I have a static IP too on that server that is 51.125.xxx.xxx
When one executes that static IP in browser, it opens defined page of php which is in /var/www/html/index.php

Postfix is installed on it. I can send mails to anywhere including gmail, rediff, yahoo. I have a share hosting server too, mail server has been configured on it. it's address is mail.domain-name.com.
I have my e-mail first-name.lastname@domain-name.com. I can send mails to this sharing hosting server too.

Now I want to receive mails on my CentOS server. I do not have any domain name for my centOS server just a static IP.

Can I receive mails on my cent OS server, if yes what should I do to receiving mails? I want to receive mails from gmail, yahoo, rediff and even that sharing hosting server too.

If I receive mail, where should I look to see the mail and how to open it.

Pleas help.

Thanks & Regards
Sam
