pcheckd(1)                                                          pcheckd(1)


NAME

       pcheckd - Checks for mail in maildir mailboxes


SYNOPSIS

       pcheckd [-l FILE, --logfile FILE] [-m DIR, --mailboxdir DIR] [-p PORT,
       --port PORT] [-e LOAD, --emptyload LOAD] [-f NUM, --fork NUM] [-r DIR,
       --rundir DIR] [-h HOST, --host HOST] [--nodeamon] [--debug] [--help]
       [--version]


DESCRIPTION

       This program will open the named UDP port (default: 50110) and listen
       for requests. It will send an answer to the requests back to the
       client.

       There are two types of requests: The mailbox request ('M') will ask the
       server about the state of the named mailbox ('0 no mail', '1 mail', '2
       new mail', or '3 load too high'). The load request ('L') will ask the
       server for the load avarage for the last minute.

       The load is returned as an integer which is determined by reading
       /proc/loadavg and cutting of everything after the decimal point.

       This server is single threaded.


OPTIONS

       --help Print short command line help.

       --version
              Print version information.

       -l FILE, --logfile FILE
              Name of logfile (default: /var/log/popular/pcheckd)

       -m DIR --mailboxdir DIR
              Directory where all the mailboxes reside. There can be an
              arbitrary depth of subdirectories beneath this. All mailbox
              names sent by the client are relative to this directory.

       -p PORT, --port PORT
              UDP port to listen to.

       -e LOAD, --emptyload LOAD
              If the system load average over the last minute is LOAD or
              higher, a 'M' request will be answered with '3 load too high'.
              In this case pproxy will fake an empty mailbox.

       -f NUM, --fork NUM
              Fork NUM processes at start of pcheckd. The parent and all the
              children will answer requests. The parent doesn't count towards
              NUM, so there will be NUM+1 pcheckd processes.

       -r DIR, --rundir DIR
              Name of run directory. The pid file is saved into this
              directory.  (default: /var/run/popular)

       -h HOST, --host HOST
              Host name or IP number to bind to. This might be needed if you
              have several IP numbers on one host. Default is to bind to
              INADDR_ANY (0.0.0.0), i.e. to listen to all interfaces.

       --nodeamon
              Don't run as daemon in the background.

       --debug
              Enable debug logging. This will log all packets as they are
              received and sent.
