Suggestions on this one would be appreciated. I provide web hosting for a local church, but they run their own email server using Exchange2k. Whenever I send email to someone at the church, I get a 550 error. Neither can they send email to me! Here's the odd part: I teach at a local university (which runs its own servers). When I log into the university's webmail system and send email to the church, that also gets bounced. I'm assuming that there might be something wrong with the MX record, but I can't figure out what it is. The domain for the church website and email server is fargohope.org. Any suggestions on troubleshooting the problem would be appreciated. -Cloy
