The only way we can tell is if you give us an heap dump. Try adding -XX:+HeapDumpOnOutOfMemoryError to the java command launching james server. This way your JVM will write an heap dump at every OOM so we can see what objects are in memory when your server throws OOM. This is a first step: if we can't find a solution this way then a real memory profiler is needed.
