=head1 NAME
|
|
|
|
syslog - Syslog logging plugin for qpsmtpd
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The syslog plugin for qpsmtpd passes qpsmtpd log messages into the standard
|
|
UNIX syslog facility, mapping qpsmtpd priorities to syslog priorities.
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
To enable the logging plugin, add a line of this form to the qpsmtpd plugins
|
|
configuration file:
|
|
|
|
=over
|
|
|
|
logging/syslog [loglevel l] [priority p] [ident str] [facility f] [logsock t]
|
|
|
|
For example:
|
|
|
|
logging/syslog loglevel LOGINFO priority LOG_NOTICE
|
|
|
|
=back
|
|
|
|
The following optional configuration settings can be supplied:
|
|
|
|
=over
|
|
|
|
=item B<loglevel>
|
|
|
|
The internal log level below which messages will be logged. Priorities count
|
|
downward as follows:
|
|
|
|
=over
|
|
|
|
=item B<LOGDEBUG>
|
|
|
|
=item B<LOGINFO>
|
|
|
|
=item B<LOGNOTICE>
|
|
|
|
=item B<LOGWARN>
|
|
|
|
=item B<LOGERROR>
|
|
|
|
=item B<LOGCRIT>
|
|
|
|
=item B<LOGALERT>
|
|
|
|
=item B<LOGEMERG>
|
|
|
|
=back
|
|
|
|
|
|
=item B<priority>
|
|
|
|
Normally, log messages will be mapped from the above log levels into the
|
|
syslog(3) log levels of their corresponding names. This will cause various
|
|
messages to appear or not in syslog outputs according to your syslogd
|
|
configuration (typically /etc/syslog.conf). However, if the B<priority>
|
|
setting is used, all messages will be logged at that priority regardless of
|
|
what the original priority might have been.
|
|
|
|
=item B<ident>
|
|
|
|
The ident string that will be attached to messages logged via this plugin.
|
|
The default is 'qpsmtpd'.
|
|
|
|
=item B<facility>
|
|
|
|
The syslog facility to which logged mesages will be directed. See syslog(3)
|
|
for details. The default is LOG_MAIL.
|
|
|
|
=item B<logsock>
|
|
|
|
The syslog socket where messages should be sent via syslogsock(). The valid
|
|
options are 'udp', 'tcp', 'unix', 'stream' and 'console'. Not all are
|
|
available on all systems. See Sys::Syslog for details. The default is
|
|
the above list in that order. To select specific sockets, use a comma to
|
|
separate the types.
|
|
|

|
|
|
|
logsock udp,unix
|
|
logsock stream
