how does one update mail?

I’ve imported  my mailboxes with the import mail script but don’t know how to update the mailboxes daily.The import selected mail script is cumbersome and does not work if i forget a day and have moved some mail and also requires i shift them to the proper mailbox.Anyone have a solution they use or since email is so integral these days will the program itself eventually take care of this?


The only possibility at the moment is to use the "import selected mail" script. V1.8 will synchronize files/folders but no mails. Maybe this will change once mbox import will be added.
