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 cyrmaster(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 generate 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 disable 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.
