FUD - provide information about user mailboxes
fud [ -C config-file ] [ -U uses ] [ -T timeout ] [ -D ]
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
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.
Read configuration options from config-file.
The maximum number of times that the process should be used for
new connections before shutting down. The default is 250.
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 Eventually it should be superceded by a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.
