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.
