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  Eventually it should be superceded by a more standards-based protocol.
