Seconded, with one exception: I got one once from a distant coworker which said “I have broken my arm in a kitten-related fall and will be out for (…)”. Everyone else uses boilerplate language so that one definitely stood out, but I thought it was the right level of mildly amusing.
By bringing some automation into the process, you not only ensure that your staff is leaving vacation email messages that cover what’s needed, but you’re also eliminating the possibility that team members will forget to turn them on.

You may not think it, but an auto-attendant is an important part of your business. It is typically the first point of contact with your customers, as they will call your main number with sales inquiries, troubleshooting questions, etc.
I wouldn’t be offended or consider saying anything to anyone who included this in their out of office message, but even as someone who is in a religion that forbids use of electronics on most holidays, I still think this message is 1) TMI; 2) doesn’t convey what it needs to convey unless you are explaining that you don’t use electronics during holidays, in which case you can just include that you won’t be checking email without including the religious explanation; 3) would come across to me as inclusion of personal information I don’t need, which would therefore strike an unprofessional tone,and I wouldn’t understand why you felt the need to include that info. How about “I’m out of the office without access to internet or email until (date). If you need assistance before this date, please contact…” Like I said, I think your colleagues are overreacting, but in general I would advise to leave all personal information out of your auto-reply — vacation, medical leave, religious observance, etc. — people do not need to know why you are out.
