pcheckd - Checks for mail in maildir mailboxes



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]


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.


--help Print short command line help.
  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 (, i.e. to listen to all interfaces.
  Don’t run as daemon in the background.
  Enable debug logging. This will log all packets as they are received and sent.
