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 cyrmaster 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 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.

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 disable 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       Eventually it should be superceded by a more standards-based protocol.
