Bounce with port 25?

... on a similar topic, I was trying to have all mail from a certain
evil ex bounce back to her, courtesy a fictional 
mail_daemon(_at_)spine(_dot_)med(_dot_)(_dot_)(_dot_)
no luck, always ended up with my name on the from line. Anyone have
a script+recipe combo that telnets to port 25 and does the suitable
forgery to accomplish this task effectively?
