IS-IT--Management
Greetings from my first post!
When I started here, we were running Exchange 5.5 on a single server. We have the internet connector installed and have pop3 and smtp defined on our external DNS. Both are defined as our external static IP address (our router's IP address).
In the router, I have a static NAT defined for both the POP3 and SMTP ports to point to our original mail server's internal IP address.
We are going through the process of retiring this original server, so I added a second server to the site and started using the administrator's tool to move mail boxes from the original server to the new server.
We have several sales people that access their e-mail remotely while they are traveling. They make an internet connection, then configure Outlook (or Outlook Express) to have have their POP3 server be the DNS entry and their SMTP server also be the DNS entry.
So long as the user's mailbox resides on the original server (the one that the router has the static NAT's to) the user is able to access their in-box from outside the network just like a standard POP3 mailbox. However, if the user's mailbox is on the new server, they are not able to access their e-mail from outside the network.
SMTP mail sent from outside the organization does get through to the appropriate mailbox, regardless of what server the mailbox is on.
What configuration changes do I need to make to allow users to access their mailbox from outside the LAN, regardless of the server their mailbox resides on?
