I have noticed that our Domain documents are not right. I have Foriegn domain documents that should be Adjacent domain docs. Any thoughts on potential problems I might run into if I change those documents?
Subject: Two Different Animals
Foreign domains are used for external applications such as fax gateways. Adjacent domains are Domino domains. They’re two different things altogether. I’d be surprised if mail was routing to another Domino domain via a Foreign domain document.
Subject: HA! Your right
Thank you for the info . I do understand the difference between the two though. That is why I need to change them. Not sure how it is routing now but it is. I just wanted to make sure that I cover everything before I make the change. It shouldn’t be a problem but I just wanted to make sure. Thanks again.
Subject: Gateways
Foreign Domains are used if there is a Gateway mailbox needed. So if your entries have Gateways entered you might run into problems…
From the Help DB:
Use a Foreign domain document to define a route from the local IBM® Lotus® Notes® domain to a gateway server that connects to a non-Domino mail system
You create an Adjacent domain document when you need to restrict the transfer of mail from one adjacent domain to another. For example, if you are in domain B and want to prevent mail from an adjacent domain A from traversing your domain to reach another adjacent domain C, create an Adjacent domain document that names C as the adjacent domain and denies mail from A.
Non-adjacent domains are IBM® Lotus® Domino™ domains that are not directly connected, but have an intermediary domain, adjacent to both of them in common. For example, domain A and domain B are adjacent and have Connection documents defining the route between them. Similarly, domain B, in turn, is adjacent to domain C and mutual Connection documents exist between them; and domains C and D are likewise adjacent to each other and linked by Connection documents. Domain B is thus adjacent to domain A on one side, and domain C on the other; and domain C is adjacent to B and D, respectively. If no direct connection exists between A and C, these two domains are considered to be non-adjacent domains. Similarly if there is no direct connection between B and D, these two domains are also non-adjacent.
Subject: Exactly what I found.
I know the differences. That is why I need to change them. I thin k the person who created them thought they were for Foreign countries… HA!! 
Thank you for the information.
