       Mail::SpamAssassin::Logger - SpamAssassin logging module


         use Mail::SpamAssassin::Logger;

         $SIG{__WARN__} = sub {
           log_message("warn", $_[0]);

         $SIG{__DIE__} = sub {

           Enable debug logging for specific facilities.  Each facility is the area of code to
           debug.  Facilities can be specified as a hash reference (the key names are used), an
           array reference, an array, or a comma-separated scalar string. Facility names are

           If "all" is listed, then all debug facilities are implicitly enabled, except for those
           explicitly disabled.  A facility name may be preceded by a "no" (case-insensitive),
           which explicitly disables it, overriding the "all".  For example:
           all,norules,noconfig,nodcc.  When facility names are given as an ordered list (array
           or scalar, not a hash), the last entry applies, e.g. 'nodcc,dcc,dcc,noddc' is
           equivalent to 'nodcc'.  Note that currently no facility name starts with a "no", it is
           advised to keep this practice with newly added facility names to make life easier.

           Higher priority informational messages that are suitable for logging in normal
           circumstances are available with an area of "info".  Some very verbose messages
           require the facility to be specifically enabled (see "would_log" below).

       log_message($level, @message)
           Log a message at a specific level.  Levels are specified as strings: "warn", "error",
           "info", and "dbg".  The first element of the message must be prefixed with a facility
           name followed directly by a colon.

       dbg("facility: message")
           This is used for all low priority debugging messages.

       info("facility: message")
           This is used for informational messages indicating a normal, but significant,
           condition.  This should be infrequently called.  These messages are typically logged
           when SpamAssassin is run as a daemon.

       add(method => 'syslog', socket => $socket, facility => $facility)
           "socket" is the type the syslog ("unix" or "inet").  "facility" is the syslog facility
           (typically "mail").

       add(method => 'file', filename => $file)
           "filename" is the name of the log file.

       add(method => 'stderr')
           No options are needed for stderr logging, just don't close stderr first.

           Remove a logging method.  Only the method name needs to be passed as a scalar.

       would_log($level, $facility)
           Returns false if a message at the given level and with the given facility would not be
           logged.  Returns 1 if a message at a given level and facility would be logged
           normally.  Returns 2 if the facility was specifically enabled.

           The facility argument is optional.

           Close all logs.
