Can we set a group email Auto-Response?

Can we set a group email Auto-Response?

Hi there,
We want to set up Auto-Responders to a Group Email address that we have set up as an external email address (the group distributes to our two Customer Service Officers.) - eg the address= support@mydomain.com.au & we want an auto response to send when someone sends something to it.

How can this be done?

Thank you very much,
