Matt, what did you upgrade from? If you jumped from 2.3.2 to 3.3 and have
custom mailets, you MAY have to recompile your custom mailets. I suggest using
at least James 3.2.0 in your maven build file James versions, if not 3.3.0.
That might mitigate some of the problems (of course, it will take some surgery
as there are deprecated classes in use from 2.3.2 that have not beencarried
into the 3.x chain).
