With all due respect, that is without any merit. The imap server does not reset UIDs at any time (nor is it allowed to). Message UIDs are how you reliably identify messages across IMAP sessions.

What would be good, were to store the md5 hash and message id (taken from the mail header) so we recognize moving messages across folders (rather than deleting and uploading it).
