logging

It seems logging is an area of qpsmtpd that is ripe for improvement, but I'm not going to toss my hat into the ring against logterse, it looks like a great solution I may adopt later. For now, I'd like to make the built-in logging a little less crusty. In attempting to figure out where it was that I needed to edit to set the logging level, I found at least 4 different places:

  •  Qpsmtpd::TraceLevel  => LOGWARN

  •  config/logging  =>  
logging/warn 4
logging/adaptive [accept minlevel] [reject maxlevel] [prefix char]

  •  config/loglevel  => 4

   •  config/plugins
logging/syslog loglevel LOGINFO priority LOG_NOTICE


I suspect the latter is an error in the plugins/logging/syslog POD, where it says: 

> =head1 CONFIGURATION
> 
> To enable the logging plugin, add a line of this form to the qpsmtpd plugins
> configuration file:

I think that it should say to place that configuration in the config/logging file. But since there's no user documentation, I had to read the other logging plugins to arrive at that conclusion.

There is docs/logging.pod, but that is strictly developer documentation. There's no document that explains to a qpsmtpd user (ie, not a developer) which of the places he needs to go and edit, and when, to get the desired effects. I'll document qpsmtpd logging, but I'd like to have a git of a historical perspective on it. 

Why/when is is necessary to edit $Qpsmtpd::TraceLevel?

Why/when is it config/loglevel consulted?  

When a plugin is chosen in config/logging, is it additive to qpsmtpd's default logging, or does it replace it?

Are the above settings how they are/were supposed to work?  Is that how we want them to work in the future?
