Here are you pumping the rest of the whole stream or till it finds the end of that particular mime part ? If yes then how you find the end of the mime part ? Because if the mime boundary is divided in a part which is already written to the file and in a part which needs to be read won't there be a problem ? -Manjula. > In this > way we do not need to know the size of the attachment upfront..
