I used imapsync to move emails from our mail server, and, while it appears the headers are correct in the imported mail (i.e. the "Sent" date shows correctly in Zimbra), the "Received Date" in the mail listbox (conversation view / message view) all show the date the mails were imported into the system. This is also effecting the search function.

I'm assuming its using an insert date in the mysql datastore, should be pretty easy to write a script to update.. right?
