Configuring Microsoft Exchange servers to interoperate with FortiMail units

Components

Description

Unlike FortiMail units, Microsoft Exchange servers do not, by default, use standard SMTP protocol to communicate with each other. If you have multiple Exchange servers and want to deploy a FortiMail unit between the servers, use the following steps to configure the Exchange servers so that they can communicate with the FortiMail unit.

The following procedure describes how to configure a Microsoft Exchange server that is running on Windows 2000 to use SMTP.
