Postfix Mail Server Setup

Hi all,
Im trying to move our email server from MDaemon to a Linux based server running postfix, dovecot & Squirrelmail.
I know how to setup the basics for the above. But here is my issue..
Our emails are remotely handled by the ISP's and our server just downloads them and allows clients to login through outlook and webmail. We have two domains.
Can someone give me clue on how to set up postfix to do the above?

Thank You So Much.

Go to /etc/postfix/ directory

Perform the following:

Code:

---


cat main.cf # displays the content of the file or

more main.cf # displays the contents, if it exceeds 80 lines, then it pauses

---

Then paste it on the screen so we have an idea of what is there.

Thank you in advance.

Todd
