Looking for an auto answer system

[Matthias Wieser <hias@sbox.tugraz.at>]

Does anybody know of an auto answering system, that should work like the
following:

you use a bit simplified language, and the system tries to answer it. if
it can not come up with a correct answer(you probably have to tell it:
no not that answer) It will add the question to queue of unanswered
questions.

This way a mailing list would have less trafic and often answered
question would just be automatically answered.

has anybody set up something like that / knows if there is a free system
around.

Thank you - mattHias
