email auto-responder

[Clemens Hermann]

Hi,

is there any template available for an email auto-responder? I need it
at the client-side so the envelope has gone yet before the mail
reaches the auto-responder script (--> response to header-FROM).
I am not necessarily looking for an out-of-the-box ready to run
solution but as my efforts spread quite a bunch of bugs over time I
would appreciate to be able to look at a working example.
