Dear all, I have gone through several on line tutorials and red several books, but I couldn't get the exact most important parameters to change or set start the postfix server in a CentOS 4.4 for single domain and separate ISP driven DNS with already MX'd.(I have setup this in sendmail working fine). Pls let me know the most important parameters for /etc/postfix/main.cf. Any online correct document, that's fine.
