Our of interest, is there an RFC or some kind of standard for out of office notifications, so that they don't get sent to mailing lists?
Ideally you'd want OoO/vacation to ignore: Precedence: list ...which Mailman is already sending. But Exchange ignores it. You could set: X-Auto-Response-Suppress: DR, NDR, RN, NRN, OOF, AutoReply ...which is an Exchange-specific header that suppresses a whole bunch of autoreplies from Exchange that you don't want. But it's a bit gross. We set it on our Nagios alerts...
I'd of expected a much higher incidence of this than we currently see.
In my (considerable) experience, people who make extensive use of mailing lists are usually savvy enough to be aware of the risks of Exchange OoO and similar. So it's rare, as opposed to common.
