If you have static IP addresses ask your ISP to put in a reverse DNS for all and any, that will fix your problem with mail servers not accepting your email. I Don't see what it has to do with your internal DNS. Your ISP owns your Internet IP addresses so your ISP must do reverse DNS for you. You can do DNS for your web and mail servers, but only name to IP not reverse (IP to name). >>From an external network, > > dig <our mail server name> > > correctly prints the IP address of our mail server and correctly prints > the DNS server names in the authority section from an external network. Of course it does, that is forward, not reverse, which you need. Forget dig, just ask your ISP for the PTR record, as Adam and I both suggested, and everything will majically work. -- Scott - : send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
