How shall the date be visible to the user?

Remember that altering the message may invalidate DKIM and other security 
/ verification stuff.

Instead of a simple "mv" you can prefix the message with "X-Date: " 
header, so you mark the message, but it is not visible to the user.

If your goal is to have the message "up" according the client side message 
sorting by date, you would need to alter the Date: header and possibly 
break message verification.

What's your goal in order to " store the date of the resubmission "?
