threading try using a real MUA)

<snip>

       Added support to provide action control (alert, drop, pass, etc)
       over preprocessor and decoder generated events, as well as references
       and classifications via a rule.  These rules do not include IP
       addresses as the individual preprocessor/decoder configuration
       dictates the traffic to which an event applies.  In conjunction
       with this, certain post-processing rule options (tag, logto, etc)
       may be added to those rules, while other options that relate to data
       inspection (content, byte_test, etc) may not.  Enable via
       --enable-decoder-preprocessor-rules option to configure.

Been there for a while.
