IMAPD(8)                                                                                            IMAPD(8)



NAME
       imapd - IMAP server process

SYNOPSIS
       imapd [ -C config-file ] [ -U uses ] [ -T timeout ] [ -D ]
             [ -s ] [ -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 master(8) with those descriptors attached to a remote  client  connec-tion. connection.
       tion.

       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  configura-tion configuration
       tion  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 shut-ting shutting
              ting 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.

       -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.
