I agree with Jason..

Mabey you should be looking at how we can enable an extensible logging
framework within James that treats messages as the logged items rather than
classes?

In other words;
log entries classified by message so that log analysis tools can quickly
extract whole histories for individual messages.
individually configurable logging (levels, locations) for mailets/matchers
that also fits in with the above.

For troubleshooting of rare issues in a high traffic (1.2 million hits/day
+) web application we use carefully designed log format which allows a
custom analysis tool to reconstruct the picture of all the concurrent
requests in progress at a single time point, this has a graphical (swing)
tree display showing the start and end time, and URI for each request
allowing the investigator to drill into the detailed log messages generated
by that request as it passes through the application. We rely on
one-thread-per-request to connect these things together, but mail logging
could use either a James issued UID or the mail UID in the headers.

Hope that helps a bit.
