A mail on the users list was asking about logging results to a database.  I was
going to say "use log_scan_result", except then I looked at the call in spamd:

  $spamtest->call_plugins("log_scan_result", { result => $log });

and $log is:

  my $log = sprintf("spamd: result: %s %2d - %s %s", $yorn, $score,
               $tests, join(",", @extra));

Which is great if all you care about is the score and the list of rules that
hit, and you feel like parsing the data back out from a scalar ...

I'd like to see several things happen:

a) Send the variables separately.  ie: $yorn, $score, $tests, @extra.
b) Include the actual message.  ie: $mail
c) Perhaps send $status, like most other calls, as well or instead, and let the
plugin figure out what to do via PMS.
d) Send some spamd information, like check() time, $current_user, client IP, etc.
