When I forward an email in Pine it goes through an outgoing filter script that I can specify. But not when I bounce an email. I don't care about literally filtering my bounced messages but I want something programmatic to happen when I bounce a message. (This is for a hack to implement an email snooze feature where you can say "make this reappear in my inbox tomorrow, or some number of days in the future".)
A roundabout way to do this would be with a daemon that monitors my sent-mail folder and notices when bounced emails appear there (ie, when the "From" is not me), extract them, and do its thing.
Is there a better way?
