This chapter contains examples of configuring the PMDF MTA and IMAP servers using a sample site as follows.

The sample site EXAMPLE.COM has two Linux nodes, naples and milan . The node naples , which has TCP/IP connections to the Internet and will be acting as a gateway for EXAMPLE.COM's Exchange users, will be a PMDF-MTA node. In addition, EXAMPLE.COM has agreed to act as a gateway for another company in town, OTHERCO.COM, and naples will will be the node which routes mail for the OTHERCO.COM node vaxa.otherco.com . milan , which is an internal EXAMPLE.COM node not necessarily registered on the Internet, will be a PMDF-MTA node, routing all of its mail to EXAMPLE.COM's Exhange users and to the Internet, by way of naples . PMDF-MTA has been installed on node naples .

Note that the sample configurations shown in this chapter only handle the base PMDF-MTA configuration with IMAP and POP mailbox servers.

Whenever appropriate, both the web-based and the command line configuration utilities attempt to provide reasonable default answers.

Remember that the values entered in this sample are for purposes of example only. Be sure to use the values appropriate for your system when you perform the actual configuration.
