4.1 Before You Begin

Prior to running the PMDF Mailbox Servers configuration utility you must have installed PMDF-MTA on your system, and it is recommended that you also configure PMDF itself (and the PMDF Service Dispatcher, normally done automatically as part of the PMDF configuration) before configuring the PMDF POP and IMAP mailbox servers. Refer to Chapter 1 if you have not already installed and configured PMDF-MTA.

If you were previously using non-PMDF servers, then you will need to shut down and disable such servers before you can use PMDF's multithreaded servers. (Before configuring PMDF's servers is a convenient time to do this, although if you prefer you can wait until after you have configured PMDF's servers but before you try to start PMDF's servers.)

The PMDF POP and IMAP mailbox servers configuration utility will prompt for several pieces of information. In particular, it will ask which POP and/or IMAP servers you want to run, and how many simultaneous POP connections and how many simultaneous IMAP connections you want to allow at your site, to which you will need to provide site-appropriate answers. For further questions, the configuration utility attempts to provide reasonable default values. You may want to mostly take the default answers the first time you configure, and then later after observing the actual POP and IMAP usage at your site, reconfigure with answers geared for your site. Configuration questions will include the following:
