NAME

showq - list the Postfix mail queue

SYNOPSIS


sshhoowwqq [generic Postfix daemon options]

DESCRIPTION

The sshhoowwqq(8) daemon reports the Postfix mail queue status. It is the program that emulates the sendmail `mailq' command.

The sshhoowwqq(8) daemon can also be run in stand-alone mode by the superuser. This mode of operation is used to emulate the `mailq' command while the Postfix mail system is down.

SECURITY



The sshhoowwqq(8) daemon can run in a chroot jail at fixed low
privilege, and takes no input from the client. Its service port
is accessible to local untrusted users, so the service can be
susceptible to denial of service attacks.

STANDARDS



None. The sshhoowwqq(8) daemon does not interact with the
outside world.

DIAGNOSTICS

Problems and transactions are logged to ssyyssllooggdd(8).

CONFIGURATION PARAMETERS



Changes to mmaaiinn..ccff are picked up automatically as sshhoowwqq(8)
processes run for only a limited amount of time. Use the command
"ppoossttffiixx rreellooaadd" to speed up a change.
