NAME
       FUD - provide information about user mailboxes

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

DESCRIPTION
       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 user.

       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  auto-
       matically 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.

OPTIONS
       -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 dis-
	      able the timeout.  The default is 60.

       -D     Run external debugger specified in debug_command.

FILES
       /etc/imapd.conf
	      Default configuration file.

       /etc/cyrus.conf
	      Cyrus Master process configuration file.

BUGS
       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  Eventually it should be superceded by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.
