CentOS - Oct 2017 - Configure an Out Of Office Reply with Postfix?

Hi,

I'm running a Postfix mail server on CentOS 7 for our local school. Some
users would like to have an out of office reply for the holiday season.
I see there is a little utility called 'vacation', and I wonder if this
is the right tool for the job.

Any recommendations?

Niki
