Suppose I want a lot of information on the cover sheet?
You want a lot of things don’t you? A MIME content-type has been defined for this. It’s called application/remote-printing. Here’s an example: Content-Type: application/remote-printing Recipient: Darren Nickerson Organization: University of Oxford Department: New Chemistry Lab Telephone: +44 1865 275975 Facsimile: +44 1865 271503 Email: darren.nickerson@balliol.oxford.ac.uk Originator: Mr. Arlington Hewes Organization: The Phone Company – International Department: Administration Telephone: +44 1234 123456 Facsimile: +44 1234 123457 Email: tpcadmin@info.tpc.int Any text appearing here would go on the cover-sheet. To use this mechanism, the top-level content in your message must be multipart/mixed, and the very first content in that must be application/remote-printing. Also, if you use this, then the left-hand part of the recipient’s address should just be “remote-printer”.
