<<1. how do we filter content,>>
It wouldn't be hard to write a pre-processor program that would scan for
words, phrases, attachments, or whatever you like.
<< and what do we filter?>>
I think that you would be better off going to the school administration
and the local school board on this one. Censorship/filtering is a sensitive
issue, especially in schools where you're funded by tax dollars. The school
board should come to a decision, and go over it with the students, parents,
and lawyers before deciding what should/should not be filtered. Otherwise,
you can land yourself at the wrong end of an ugly lawsuit. Whatever you
decide to filter/censor, make sure that you are open and frank that you
*will* be filtering it out.
Then, of course, remember that it's trivial to encrypt messages so that
filtering won't work. : )
<<2. notification of abuse. ( How do we forward the bad stuff to the
appropriate administrator?)>>
The pre-processor program could simply forward questionable email to the
admin, could make an netry in a log file, or anything else that you wanted.
