You are right moving the mail should be simple.
I ask myself it is possible to store the date of the resubmission in the mail itself.
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 "?
My goal is to use IMAP only, not external database. But I guess this is not possible.
I could alter the subject of the mail. What kind of message verification could break?
