    Generally an A record for the host and an MX record for the domain pointing to the A record for the host with postfix.

    IE, the IP for postfix is 1.2.3.4 . You want to send mail from mysoopercooloffers.com..

    IN MX 10 mx.mysoopercooloffers.com.
    mx IN A 1.2.3.4

    Spf and DKIM are text records.

    SPF tells supporting recipient servers which IP addresses are authorized to send email on behalf of your domain. You can learn more here: http://www.mtgsy.net/dns/spfwizard.php

    DKIM is a way of signing your message headers/body with a private key and your domain zone holds the public key to check against. There's a web based tool for generating private/public keys.. http://www.dnswatch.info/dkim/create-dns-record

    If you have some specific questions I can answer them for you but your post is pretty broad.

    For DKIM the easiest way IMO is to just use webmin/virtualmin.

    http://www.webmin.com/download.html

    It will automatically append the milter lines to the end of your main.cf for postfix.

    SPF is all done in your DNS records at Godaddy or wherever you're running the domains from.
