dnsblog [generic Postfix daemon options]
The dnsblog(8) server implements an ad-hoc DNS allow/denylist lookup service. This may eventually be replaced by an UDP client that is built directly into the postscreen(8) server.
Problems and transactions are logged to syslogd(8) or postlogd(8).
The text below provides only a parameter summary. See postconf(5) for more details including examples.

- The default location of the Postfix main.cf and master.cf configuration files.

- How much time a Postfix daemon process may take to handle a request before it is terminated by a built-in watchdog timer.
