Internaly it is working correctly.
Know I wont send mails out side and revice mails from outside.
How can I do this do I have get REALIP address and doamain from my ISP or cann't I do it with a dial up connetion.
You will have a real tough time doing this with a dial up connection. The recieving part is going to be the hurdle hardest to jump. If you have to use a dial up connection, you are usually better off having the emails stored elsewhere (an mx backup), and then retrieving them at given intervals.
To make it easy to send you stuff you should have one, but technically no you don't have to have one. You can use your IP. For example, if you had IP 1.2.3.4 and you had a user named dude, then you could send mail to:
dude@1.2.3.4
And if everything went well (your ISP doesn't block the port, your mail server works correctly), you should recieve the mail.
