Is there a way i can use a rule or "timer" of some sort to turn on out of office, or enable an auto reply for 1 mailbox (Sales mailbox) within a time period.

Reason:

We deal with all timezones, we only open 6am-8pm. critical sales are sometimes lost the automatic reply will involve a telephone number for emergency sales. (yes, spam i know)

I wish the auto reply to come from "[email protected]" if this is possible. I've lokekd at transport rules, cant see anything.

I cant word my question well enough for google to give an answer.
