It is so odd that some people here don't like to answer to the users questions and forwarding them to read a book with 496 pages.

The gap between what your questions suggest you know, and what you need to know to operate a mailserver is too wide to be adequately bridged on this mailing list. Asking questions here is no substitute for taking the time to purchase and read some books on DNS, and Postfix. For Postfix, the "No Starch Press" book by Ralf Hildebrandt and Patrick Koetter is a good start, and may even get some of your DNS questions answered. You can start there, and if you still have DNS questions, also read a DNS book. -- Viktor.
