Wow.  Glad to see things calmed down.

Mailman is an answer to most of your problems, you just need to remind
people to turn not let their vacation message post to lists.  After
installing Mailman 2.1 (most current stable version), you will have a web
administrative interface to your mailing lists.  Once there you can set
moderation options.  There are quite a few options to set and change. Visit
http://www.list.org/features.html for a list of most of the features.

You can set the list to member post only, and then set the moderation flag
for everyone on the list (except for thoes you want to allow thru).  Then
when a post is made to the list by someone that is moderated, you will get
an email telling you of that post, then you have the option to
Discard, Allow, Defer or Reject the message.

I think you will like Mailman 2.1.
