some mail clients (at least pine) don't show the headers when you view the attachment.
As far as pine goes, if you start viewing the headers on the main message, then step into the attachment, it will show any headers in the attached message.
Commands would be: h (show headers) > (step into attachment structure) select the attachment > (step into attachment)
