One thing that happens when you regularly send a newsletter out to tens of thousands of people is that you see a lot of automatic Out Of Office (OOO) email responses. The most common one I receive goes something like this: Hi, I’m out of the office until __ and may be slow to respond to email. If it’s an emergency, you can reach me at __ or please contact __. Thanks!

Yeah, it’s very strange. I understood changing voicemails to explain that the line can’t actually be answered, but someone is checking the messages and will respond (though that was also only an issue for the first few months), but they had no reason to even mention it for email.
