You never said if your emails were being returned or simply not being delivered (blackholed). If they are being returned as "undeliverable", check your configuration, and the email addresses, as the problem IS on your end. If they are being "blackholed", you need to see if you have been blacklisted AND check your configuration. What do you mean by "fake email with .net email account"? If you just created a ".net" email account locally on your own mail server, that isn't going to test anything. If you mean you acquired a free email account with a ".net" extension to test with and your email worked, but still does not work with an ISP provided ".net" email, then you should check if your domain has been blacklisted by the ISP mail servers for some reason. I think DNS Stuff (http://www.dnsstuff.com/) has some free tools you can use to help diagnose your problems.
