mail enabled java application

Hi, we need a java application that processes emails from a postbox and creates a timesheet out of them. This application had already been written by another sub-contractor but it has too many bugs and so we rediecided to rewrite it. We would like that you use the attached xml-schemas, but please verify if there are inconsistencies in the schemas and in case correct them. A simple java program which reads emails from a postbox is attached. Please read the attached specification. Thanx and kind regards C.
