Description

Currently an org.apache.james.mime4j.message.Message uses temporary files to store text and binary attachments of the message. Unfortunately a Message cannot be disposed of explicitly. Even when it eventually gets garbage collected the temp files continue to exist until the VM exits.

If the VM runs for a long time and a lot of e-mails get processed this can become a major problem.

For this reason I think that class Entity and interface Body should both have a method to dispose of the object. Multipart should dispatch a dispose-call to its list of body parts. A BodyPart should dispose of its body and concrete Body implementation such as TempFileTextBody should ultimately invoke delete() on the backing TempFile.

Last but not least SimpleTempStorage$SimpleTempFile should not silently ignore delete-calls.
