I see from your > idea of using headers that that wasn't a valid assumption to make. i'd also assumed that the meta-data storage should be separate but it's good to try to consider every approach :-) when server emails over HTTP, meta-data could be naturally associated by using webDAV extensions.

MIME sounds interesting :-) plays well with forwarding and so on sounds like progress: i have a little clearer idea now about what a meta-data aware server might look like: engines on the way in to attach meta data; processors would be able to retrieve meta-data as well as original email content; on the way out, serializers would use this meta-data in some way to process the original email: perhaps by attaching selected data to the email as a MIME attachment.
