I send you mail with a job application. You accidentally delete it and
request I provide it again. I enter my sent mail folder and use the
bounce facility in Mutt to resend the mail. The procmail rule deletes
it. At some point I may start to wonder why I never made the short-list.
"Be strict in what you send and generous in what you receive" is still a
good maxim to follow.
