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.
