Hi Tim, The MIME-Multipart DataFormat uses javamail as the underlying technology. The DataFormat is using streaming as far as the DataFormat is concerned, but I fear that javamail as such keeps a lot of stuff in memory so there is very likely no full streaming with that component available. For marshalling this might work with streaming as long as the component providing the Camel Message with its attachments is stream capbable, but for unmarshalling, I think that the javamail component will create ByteArrayDataSources at least for the attachments.

I was looking at the MIME-Mutipart DataFormat and it looks very useful: https://camel.apache.org/mime-multipart.html But I was not sure if it fully streams the data for the body and attachments, or whether it holds the content in memory (this is for both marshalling and unmarshalling). Thanks Tim
