       FUD - provide information about user mailboxes

       fud [ -C config-file ] [ -U uses ] [ -T timeout ] [ -D ]

       FUD is a long lived datagram daemon started from master that provides
       information about when a user last read their mail, when mail last
       arrived in a user's mailbox, and how many messages are recent for that

       Note that for FUD to run properly you must set proto=udp in its
       cyrus.conf services entry.  prefork=1 is also recommended.  FUD will
       automatically proxy any and all FUD requests to the appropriate backend
       server if it is runing on a Cyrus Murder frontend machine.

       FUD reads its configuration options out of the imapd.conf(5) file unless
       specified otherwise by -C.

       -C config-file
              Read configuration options from config-file.

       -U uses
              The maximum number of times that the process should be used for
              new connections before shutting down.  The default is 250.

       -T timeout
              The number of seconds that the process will wait for a new
              connection before shutting down.  Note that a value of 0 (zero)
              will disable the timeout.  The default is 60.

       -D     Run external debugger specified in debug_command.

              Default configuration file.

              Cyrus Master process configuration file.

       Though not really a bug, FUD will silently ignore any requests that it
       does not consider valid.

       Also not really a bug, FUD requires that the anonymous user has the 0
       (zero) right on the mailbox in question.  This is only a "bug" because 0
       is not a standard IMAP ACL bit.

       FUD is an experimental interface meant to provide information to build a
       finger-like service around.  Eventually it should be superceded by a more
       standards-based protocol.
