You do NOT want to setup an autoresponder like vacation!  The
FEATURE method that Giorgos explained is the correct way to do it.
If your not using sendmail and your MTA cannot issue an error in
this fashion, you do not want to mess around with this.

What happens with autoresponders is that spammers inadvertantly
trigger them.  As a result the autoresponses get sent to thousands of
victims who had their names forged to the spammers message.  Some
of those victim addresses are spamtrap addesses.  With the result
that if you setup an autoresponder and a spammer hits it, your
site will get blacklisted.  The Sendmail method does not have this
problem because the error message is returned during the transmission
phase, to the sending mailserver, it is not e-mailed to the envelope
address.

An autoresponder that only sends autoresponses to a defined list of
senders is OK.  But one that sends to anyone is a Bad Thing!
