get more details in JSON logs

[Damian]

> For about 5 years now I'm using JSON log output of Amavisd to feed logs into a Splunk indexer. It's incredibly useful on a daily basis and I would like to extend this a little bit: is it possible to get in the JSON log entry of a message the listing of files names attached to the message?

If you are logging via a $log_templ macro, this is not possible as far
as I can tell. If you log into redis, this "config" snippet might work
for you. No guarantees, though.
