WRITING PLUGINS
    Plugins for SyslogScan::Daemon::BlacklistDetector should subclass
    "SyslogScan::Daemon::BlacklistDetector::Plugin". Except for "new()" and
    "preconfig()", all of these methods are optional.

    SyslogScan::Daemon::BlacklistDetector will invoke the following methods
    on its plugins:

    new()          See notes for plugins for SyslogScan::Daemon.

    preconfig()    See notes for plugins for SyslogScan::Daemon.

    get_logs()     See notes for plugins for SyslogScan::Daemon.

    parse_logs()   Called after one of the regular expressions returned by
                   "get_logs()" matched a log line. The arguments are the
                   log filename where the match was found and the regular
                   expression that matched. Passed implicitly are the line
                   that was matched ($_) and any of the numbered regular
                   expression submatches ($1, $2, etc).

                   The return value is a %hash of information. The hash
                   should be completely empty if the log line is not a SMPT
                   rejection.

                   The following keys are required:

                   status         This should be "deferred" for a 4XX
                                  rejection and "bounced" for a 5XX
                                  rejection.

                   logline        This should be the whole log line ($_).

                   sourceip       The IP address used by the MTA for sending
                                  email. This may be "unknown".

                   destdomain     The domain of the recipient that bounced.

                   to_address     The recipient that bounced.

                   The return value is the %info hash passed to exactly one
                   of the following: "grelisted()", "recipient_reject()",
                   "sender_reject()", "content_reject()"
                   "realtime_reject()", and "blacklisted()".

    greylisted(%info)
                   This is called if the "logline" returned by
                   "parse_logs()" contatins the word "greylisted".

    recipient_reject(%info)
                   This is called if the "logline" returned by
                   "parse_logs()" matches a regular expression that
                   indicates that the rejection was due to being sent to a
                   particular recipient.

                   The regular expression is hard-coded to encourage
                   everyone to share any changes with the author.

    sender_reject(%info)
                   This is called if the "logline" returned by
                   "parse_logs()" matches a regular expression that
                   indicates that the rejection was due to being sent from a
                   particular sender.

                   The regular expression is hard-coded to encourage
                   everyone to share any changes with the author.

    content_reject(%info)
                   This is called if the "logline" returned by
                   "parse_logs()" matches a regular expression that
                   indicates that the rejection was due to the content of
                   the message sent.

                   The regular expression is hard-coded to encourage
                   everyone to share any changes with the author.

    realtime_reject(%info)
                   This is called if the "logline" returned by
                   "parse_logs()" matches a regular expression that
                   indicates that the rejection was due to a transitory
                   blacklist.

                   The regular expression is hard-coded to encourage
                   everyone to share any changes with the author.

    blacklisted(%info)
                   This is called for lines that don't match the regular
                   expressions for "grelisted()", "realtime_reject()",
                   "sender_reject()", or "recipient_reject()" or
                   "content_reject()".
