exim, email, and dns

I am trying to set up my own email server. I had problems with sendmail so I switched to exim. I have exim up and running correctly (I think) but I think now I have dns issues. I have a real domain that i'm trying to set up, but when I send email to some accounts they bounce back with a 550 error, but others are fine and accept the email. I figure this is some spam blocking thing and that my dns must be messed up and that I look like a possible spam server.

Here is the error i get back form to different emails that i sent.

SMTP error from remote mailer after RCPT TO:<>: host []: 550-Verification failed for <> 550-unrouteable mail domain "" 550 Sender verify failed

and the other is

SMTP error from remote mailer after MAIL FROM:<>: host []: 550 5.0.0 Use your ISP's SMTP server

Does anyone have an thoughts about how to fix my problem.
