- don't respond to bounces, spam and viruses
- don't respond if the rcpt isn't in To/CC/Resent-TO/Resent-CC headers
- don't respond to an auto-response (or to any automatically generated
mail unless that is part of your auto-responder job)

you get the whole mail.
now, reinventing the wheel is a risky thing. why not use the vacation
program?
