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...

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.
