This is true! The nuclear option also helps the recently returned vacationer understand what is a priority and what isn’t. But, as boyd wrote, “if you just turn off your email with no warning, you're bound to piss off your friends, family, colleagues, and clients.” The blog post offers some helpful steps to make a clean break feasible — they include communicating with colleagues about the sabbatical long in advance, managing expectations of those who rely on you, creating a backdoor for true emergencies, and then, right before going away, reminding everyone about the sabbatical once again.
Don’t beat around the bush! This is an expression that means you should get to the point. That is, you should make your message direct and brief. This will let the recipient quickly know that you’re not available and who they can contact instead. You can start with a simple greeting and then proceed to the message like in the following examples:

If those weren’t bad enough, if anyone on that lists sets up an out-of-office message, it *automatically* replies all. If the email bounces back, it bounces back reply all. One guy left the company and his email had a permanent out-of-office auto reply. The list was quite busy for a month or so and the message popped up multiple times a day.
I saw a version of this on IG that was an old school (paper) OOO from an associate pastor. It has a line like “if this is an emergency and you must speak to someone, Jesus is always available on the mainline.” Too funny.
