NAME

       qpsmtpd-prefork - Preforkin server for qpsmtpd

SYNOPSIS

       qpsmtpd-prefork [options]

DESCRIPTION

       qpsmtpd-prefork  is  the  qpsmtpd  frontend script which binds to the SMTP TCP socket, and asynchronously
       forks new children in advance of new connections.

OPTIONS

       --port port
              Binds to a specific port, instead of the default 2525.

       --user user
              On startup, switch to run as user instead of the starting user.  Applies only when started as root
              (as is normal when listening on port 25).

       --limit-connections limit
              Accept at most limit simultaneous connections.   Inbound  connections  beyondthis  limit  will  be
              deferred or refused.

       --max-from-ip limit
              Accept  at  most  limit  simultaneous  connections  from  any  given IP address; does not override
              --limit-connections, if set.

       --children limit
              Limit the total number of child processes to limit;  once  all  children  are  handling  requests,
              further connections are deferred.

       --idle-children count

              Keep  count child processes available, subject to the upper bound given via --children.  Specify 0
              to disable preforking entirely.

       --interface addr
              Bind to the local address addr, instead of the default behavior of binding to all interfaces.  Can
              be specified multiple times to bind to more than one interface or local address.

       --renice-parent delta

              Adjust the priority of the parent process by delta, yielding more CPU  time  to  other  processes.
              The default is 5.

       --detach
              Detach  from  the controlling terminal at startup, to run as a standalone daemon.  See also --pid-
              file.

       --pid-file filename
              Upon startup, and after daemonizing if applicable, write the process ID to filename,  for  use  by
              sysvinit control scripts or similar utilities.

       --pretty-child

              Update child process names within the process table.

       --version
              Print the qpsmtpd release version and exit.

       --debug
              Be somewhat more verbose about logging during startup (has no effect once fully started).

       --help Display commandline help and exit.
