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(5) 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

   Use the specified configuration file *config-file* rather than the
   default imapd.conf(5).

-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, /etc/cyrus.conf


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superceded by a more standards-based protocol.
