Problem with this is does it scale, and can it be used on a complete mail
server.
I guess you *could* use procmail as your MDA and then filter on stuff
going into user mailboxes, but that tells you who is receiving
obscenities, rather than sending them. There is no good way of putting
this into the outgoing stream (or could you add it as a transport
filter....?).
Even so, each word you go for is requiring a grep of the body. A few 10MB
emails with 30 words looked for in each might well do interesting things
to your server load (or just run out of memory - procmail tends to eat it).
BTW when looking at my exim filter example, remember that the
$message_body is limited to 500 characters by default.
