The PMDF POP and IMAP servers are multithreaded and run under the control of the PMDF Dispatcher. The PMDF legacy mailbox POP server can serve out native BSD mailboxes or PMDF popstore mailboxes; the PMDF legacy mailbox IMAP server can serve out native BSD mailboxes. The PMDF MessageStore mailbox POP server can serve out PMDF MessageStore mailboxes and PMDF popstore mailboxes; the PMDF MessageStore IMAP server can serve out PMDF MessageStore mailboxes. The PMDF mailbox servers configuration utility allows choosing one or the other POP server and one or the other IMAP server. (PMDF supports running both POP servers, one of which must then be running on a non-standard port, and running both IMAP servers, one of which must then be running on a non-standard port, but such configurations are not generated by the configuration utility.)

The POP and IMAP servers may run on a PMDF-MTA system.

This chapter describes how to use the PMDF Mailbox Servers configuration utility. This utility generates definitions for POP and IMAP servers to insert into the PMDF Dispatcher configuration, as well as basic PMDF POP and PMDF IMAP server configuration files. It also provides a checklist of the steps you need to take to complete the configuration of the PMDF POP and IMAP servers.
