I have a number of rules in Mail.app (these ones work!) to move e-mails which are X days old to trash.
I'd like to run these rules at a specified time, eg: midnight. In this case, the particular rules will move e-mails which are older than 1 day to trash.
I use Mail Act-On and Mail Tags, but cannot find any functions there.
Is it possible with Mail.app natively? If not, is it possible with some plugin? Ideally open-source.
