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.
