I have an exchange box that routes all of my mail in and out. I am having some issues with e-mail that is going out and I think it is related to reverse dns lookups. SMTP Users send out e-mail swith a [email protected]com e-mail address but my mx record list my exchange box is mail.company.U]net[/U]. is this a potential problem? I hope I am making sense ,when I ask this question. Thanks Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
