System_Configuration

   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 see under PMDF Pine System_configuration
   UCX Emulation and PMDF Pine System_configuration Subprocess Quota
   for descriptions of two installation issues to check, and see
   under PMDF Pine System_configuration Configuration Files for a
   description of 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.
