Hi Tommy,
Thanks for noticing it and raising the issue, it is a concern indeed. We
forgot to inform you but we started working on it, a PR has been
proposed for moving to log4j2 :
https://github.com/linagora/james-project/pull/3214
Please take a look if you have time. Don't hesitate to try or give
comments as well.
Regards,
Rene.

Hi David,
Which knob(s) on the logging configuration did you turn on? Have you tried
org.apache.james.protocols? I just looked briefly through the codes for
3.4 and I think this one may help you even though the code doesn't log as
much like springframework at debug level.
Despite using version 3.3.0 myself, but seeing Malcom's assertion that
logging setup had changed in 3.4.0, I just used the file he posted with
very little change, just one or two flips from INFO to DEBUG.
Prior to that my 3.3.0 setup was only writing to the james-server.log and
wrapper.log, but now there is additional logging in other log files. What I
particularly missed was having some feedback from remote mail exchangers
that I sent mail to and that is now satisfied in part at least. So it's now
less of a concern.
Was interested to read that you said (I think) you had 3.3.0 running on
java 11 as that doesn't work for me. I have to run a java webmail client
(of james running in java 8) in java 11 (!) to make imaps work. I've think
I read somewhere that's a java 8 bug though.
I wanted to run James on Java/JDK 11 because Java 8 is going away in about
a year. I didn't want to spend time setting it up only to get it working
again later on JDK 11. Also, IMO, I don't think EOL software should be
used in production due security risks especially when a viable replacement
is available. The only reason that I could think of thus far, from both
looking at the jars and partly in code, is the log4j (v1) dependency. If
you replace the log4j with log4j2 jars and the appropriate configuration
file, you should be good to use later versions of Java. This is what I did
to get James running on Java 11:

I've added few extra log4j2 bridges to see as much logging as possible in
case any of the other dependencies uses other then log4j2 and updated the
slf4j to most current 1.7.30 instead of 1.7.25 for security. Here's my
log4j2 configuration file:
https://github.com/tommyhp2/ajs/blob/master/src/main/webapp/WEB-INF/classes/log4j2.xml
Feel free to use and change as needed. While typing this up and looking at
the list of jars above, you could also remove the jcl-over-slf4j jar also.

Tommy
