Smart Mailbox Migration

Hi all,

I put significant work into creating Smart Mailboxes that really improve my experience with the Mail app. I recently had a logic board replaced and restored my data from a manual backup of my home folder. This apparently did not include the settings in the mail app, and especially my Smart Mailboxes, which I had to meticulously reconstruct. Is there a way to export/import my Smart Mailbox "rules" so that they can be restored without using the migration assistant? I've always been a fan of manually restoring as many settings like this as possible in case some of my other system settings are not desirable on a new machine. In this way, I get to use some default settings, while only preserving ones that I consider important. It's also worth noting that I don't generally use iCloud, as it is too difficult to take advantage of some of its conveniences without exceeding the free data limit. I suppose if there is a low-data approach to preserving mail settings, not individual emails, with iCould, that could be acceptable.
