ResendingMailWithHeaders

Good morning,

I am wondering if it is somehow possible to redirect a mail from the a user’s mail file without changing the headers. This is possible different mail clients, eg. Netscape, Outlook etc. This should be used in relation with SpamAssassin:

I know this sounds like a lack of security if this is possible, but still wondering if it is possible.
