NAME

       imapd - IMAP server process

SYNOPSIS

       imapd [ -C config-file ] [ -U uses ] [ -T timeout ] [ -D ]
	     [ -s ] [ -N ] [ -p ssf ]

DESCRIPTION

       Imapd  is  an IMAP4rev1 server.	It accepts commands on its standard input and responds on its standard output.	It MUST be invoked by cyr-
       master(8) with those descriptors attached to a remote client connection.

       Imapd reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.

       If the file msg/shutdown is created under the directory specified in the configdirectory configuration option, then imapd  will	shut  down
       the connection, sending the first line contained in the file to the client as the reason.  New connections are denied.

       If  the	file msg/motd is created under the directory specified in the configdirectory configuration option, then imapd will send the first
       line contained in the file to clients upon connect as an ALERT message which IMAP-compliant clients are required to display.   This  option
       serves  to annoy users mostly.  Unfortunately clients tend to connect far more frequently than is apparent, causing each connection to gen-
       erate a seperate server ALERT for each connection.  Many clients do not display these properly, if they do anything with them at all.

       If the directory log/user exists under the directory specified in the configdirectory configuration option, then imapd will create protocol
       telemetry  logs	for  sessions  authenticating as user.	The telemetry logs will be stored in the log/user directory with a filename of the
       imapd process-id.

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 dis-
	      able the timeout.  The default is 60.

       -D     Run external debugger specified in debug_command.

       -s     Serve IMAP over SSL (imaps).  All data to and from imapd is encrypted using the Secure Sockets Layer.

       -N     Bypass password checking.  (Not recommended unless you know what you're doing.)

       -p ssf Tell  imapd  that an external layer exists.  An SSF (security strength factor) of 1 means an integrity protection layer exists.  Any
	      higher SSF implies some form of privacy protection.
