DNS Issues?

I'm having trouble with my emails getting blocked. Yahoo! Mail told me to go to this link and fix it, http://www.saas.nsw.edu.au/solutions/dns.html but I don't understand most of it. I'm running my own email server (Capesoft Email Server) and Yahoo! Mail keeps rejecting emails from us because of some DNS problem. I need help understanding this article and how to go about setting up my DNS. I have no knowledge on how DNS works so I need a fairly basic breakdown. Like, go to blah and do blah to set your blah to the right IP Address. Thanks.

I'm using the... DNSey kind of DNS Server.... Like I said, I'm not actually sure how DNS works. I'll tell you what servers I'm running and where my domain comes from, I'm running my email server and webserver off of Server 2003. My email's handled by a Capesoft Email Server and I get my domain name from GoDaddy.com. I'm not entirely sure if that helps you out but hopefully that answers your questions.

Oops, I meant to say server 2000, 2003 is my database server...

Ok, so can someone explain how the whole DNS thing works? How do you configure "Your DNS" All I know is that DNS stands for Domain Name Server... Beyond that I know nothing of how it works.

Sweet, thanks for the link actually that helped a lot. So I made the PTR record, my MX, CName and A records are all pointed correctly. Is there anything I'm missing?

Atleast from the DNS part that should be all SG.
