NAME
dnsblog - Postfix DNS white/blacklist logger
SYNOPSIS
dnsblog [generic Postfix daemon options]
DESCRIPTION
The dnsblog(8) server implements an ad-hoc DNS white/blacklist lookup service. This may eventually be replaced by an UDP client that is
built directly into the postscreen(8) server.
PROTOCOL
With each connection, the dnsblog(8) server receives a DNS white/blacklist domain name, IP address, and an ID. If the address is listed
under the DNS white/blacklist, the dnsblog(8) server logs the match and replies with the query arguments plus an address list with the
resulting IP addresses separated by whitespace. Otherwise it replies with the query arguments plus an empty address list. Finally, The
dnsblog(8) server closes the connection.
DIAGNOSTICS
Problems and transactions are logged to syslogd(8).
CONFIGURATION PARAMETERS
Changes to main.cf are picked up automatically, as dnsblog(8) processes run for only a limited amount of time. Use the command "postfix
reload" to speed up a change.
The text below provides only a parameter summary. See postconf(5) for more details including examples.
config_directory (see 'postconf -d' output)
The default location of the Postfix main.cf and master.cf configuration files.
daemon_timeout(18000s)
How much time a Postfix daemon process may take to handle a request before it is terminated by a built-in watchdog timer.
postscreen_dnsbl_sites (empty)
Optional list of DNS white/blacklist domains, filters and weight factors.
ipc_timeout(3600s)
The time limit for sending or receiving information over an internal communication channel.
process_id (read-only)
The process ID of a Postfix command or daemon process.
process_name (read-only)
The process name of a Postfix command or daemon process.
queue_directory (see 'postconf -d' output)
The location of the Postfix top-level queue directory.
syslog_facility (mail)
The syslog facility of Postfix logging.
syslog_name (see 'postconf -d' output)
The mail system name that is prepended to the process name in syslog records, so that "smtpd" becomes, for example, "postfix/smtpd".
