My problem is that occasionally an Out-of-office message is broadcast to the
entire list. However, this is an exceptional behaviour, which does not
normally happen when users have activated their Out-of-office Assistant (or
whatever it is called).

I have browsed the archives concerning handling of Out-of-office messages,
and as I read the archives there are no settings you as a list owner can
set. Everything depends on the settings at the "offender's" computer (and
possibly also on settings with the person who posts a message).

There are seemingly only two things to do about it:

1. If an o-o-o message is broadcast you can remove the "offending" user from
the list, either temporarily or permanently.

2. You can "educate your users" to configure their Out-of-Office Assistant
properly.

But now, my question is: How do you "educate your users"? Does anyone have
sample texts which you can send, either to an "offending" user or to the
entire list?
