Daimler's Solution For Annoying Out-of-office Email: Delete It
AmiMoJo writes Sure, you can set an out-of-office auto-reply to let others know they shouldn't email you, but that doesn't usually stop the messages; you may still have to handle those urgent-but-not-really requests while you're on vacation. That's not a problem if you work at Daimler, though. The German automaker recently installed software that not only auto-replies to email sent while staff is away, but deletes it outright.
Out Of Office = "I'm not going to get a timely reply"
Email's strength is that it is asynchronous. I send CC emails to people that I know are not available because I want them to read it when they get back, so they aren't totally clueless as to what happened while they were out scuba diving or whatever.
Occasionally living proof of the Ballmer peak.
You don't have to check it while you are on vacation. You can actually ignore it.
So why delete what could be important communication? Just deal with it when you are back in the office.
I think the point is to not have work pile up while on vacation. I do not think people use "out of office" for after work hours.
Some of the people I work with use "out of office" for weekends. It's a passive-aggressive way of fighting back against the corporate expectation that everybody will login for email 24/7 (an expectation that got worse as corporate-issued mobile email devices got pushed further down the ladder).
