Automatic export messages Rated 4 out of 5 stars

Hello! Thanks for addon ImportExportTools, it does just what I need - export mail messages to HTML from selected folder.
Just want to know - is there some possibility to do export automatically? Had found option about pereodical backup, but it is not export.
Can you help me with that? Maybe I shoould use another addon?
