PMDF Pine uses PMDF extensively. PMDF must be installed and configured on the system for Pine to function. Pine uses PMDF to send mail, to parse addresses, and to save copies of messages you have sent, if the Pine default-fcc option is set. Once PMDF is configured and installed on a system, PMDF Pine is usually ready for use, although Section 7.7.1 and Section 7.7.2 below discuss two installation issues to check, and Section 7.7.3 below describes tailoring the Pine environment on a system wide basis.

In particular, note that Pine does not, by default, use IMAP to talk to your local system, so it is not necessary to have an IMAP server running on your system just to use Pine. (Only if a user were to specifically request that Pine treat the local system as if it were instead a remote system with an IMAP server, by specifying the imap-host field when accessing a folder collection, would PMDF Pine attempt to make an IMAP connection to the local system.)

Pine is installed by PMDF with the privileges SYSPRV and CMKRNL. Without those privileges, users can not send mail, although they can still read mail.
