Automate Email Import

Greetings,

I’d like to have DT’s Apple Mail Import run on my “archive” mail folder once every night, importing just newly archived messages. This is the feature available from File->Import->Email.

I’ve looked around the forum and don’t see a way to automate this. I know it is possible to setup mail rules, but the Apple Mail Import feature places the messages in a special hierarchy and skips duplicates, which is exactly what I want. I could probably write a custom Applescript but, before going to that extreme, is there an easier way to do this?

Thank you for any insight!
