qmail and auto-reply

[Kaare Rasmussen]

Hi

I have some users on a qmail mail system. It works very well, but some
have requested a facility to make an auto-reply function for whenever
they are on vacation.

Does anybody know a solution for this, taking into account that the user

should be able to update the reply and dates (and they are only mail
users, not shell users) and that it preferably should run with virtual
mail uders ?

Thanks in advance.
