At a first thought I think that MimeMessageWrapper should never be used
directly. Uses of previous MimeMessageWrapper have been replaced with
MimeMessageCopyOnWriteProxy.
Now we keep the MimeMessage shared much more than before, maybe this
will make bad usages to show up.

Is there something that we need to document generically for all of the users who do have custom mailets?

Ask him informations on his configuration.
If I know something more of "server issue" I can try to give some hints
to some of the problems that could be caused by MimeMessageWrapper and
the CopyOnWriteProxy.

Just committed a version that at least compiles. IM'ing Vincenzo as he works through debugging the server issues (again, he has no e-mail access).

This is not really tested. I modified an existing test mailet of mine to do more logging, and committed it as we had discussed at ApacheCon. I rushed through this right now because Vincenzo is having problems with JAMES v2.3 on his production server, can't send mail at the moment, and should benefit from this in debugging.
