The default is 250. .TP .BI \-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. .TP .BI \-D Run external debugger specified in debug_command. .SH FILES .TP .B /etc/imapd.conf Default configuration file. .TP .B /etc/cyrus.conf Cyrus Master process configuration file. .SH BUGS Though not really a bug, .B FUD will silently ignore any requests that it does not consider valid. .PP Also not really a bug, .B 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. .PP .B 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 Eventually it should be superceded by a more standards-based protocol.
