Wondering if anyone monitoring the list can assist me with a problem I'm having trying to get inbound mail on my exchange server? I'm using TZO for my web hosting and they also manage the MX record for the domain. I use Bellsouth for my ISP and I know they're not blocking email or port 25. My home network looks like this: Exchange 2000 running on Windows 2000 Server. This server is on a Windows 2003 network. I've created a host record for the Exchange server using an internal private IP and I've also created a host record for mail that contains the IP of my ISP. So I have: exchangesrvr - 192.168.x.x - Internal static IP mail - 205.152.x.x - Bellsouth DNS server IP My MX record also points to the mail record that contains the Bellsouth IP. My domain is www.nubiint.com and the mail server is mail.corp.nubiint.com. This obviously doesn't work because I haven't seen any documentation that states to do it this way. Is there anyone monitoring who's familar with TZO that can break this down for me? Many thanks in advance
