Replying to I need some help (school)

i wrote this dank essay which got me an A... the problem is that i turned it in 3 days late so it was marked down to a B. Cuz im trying to slay this class quick' I lied and told my professor that i emailed it that night it was due like we are allowed to do, but then checked my email a couple days later and noticed that I must of spelled her email wrong because it bounced back to me.

Its pretty simple I just need to forward her the returned email (like mailer-daemon or whatever the auto-service its) as proof that I sent it that night and she will bump it back up to an A . I know theres some smart kids here , theres got to be an easy way to forage the bounced-back email so I can get the grade I deserve. any ideas? i got photoshop , whatever i need
