I'm setting up an Exchange Server on the outside of a firewall. This server
will be handeling all internet mail for our company and will be using the
X400 connector to pass this along to the rest of the Exchange envirinment on
the inside of the Firewall.

Does anyone know what ports need to be kept open other than port 25. (X400
etc...)


Thanks,


Stefan Buchman

Why have the server on the outside of the firewall.
I would suggest leaving it inside then and leaving port 25 and 110 open for
POP3...or port 143?? for IMAP4.

Start with this MS KB article:
Q176466 "XGEN: TCP Ports and Microsoft Exchange: In-depth Discussion"

There are other KB articles describing how to configure Exchange to
use static port assignments. There is a section in the platform API
reference on controlling the assignment of dynamic port number ranges
used for RPC.

Most X400 systems use port 104 for communicating over IP.
But you can change default settings using registry editor.
