Can anyone suggest the best way to impose outgoing limits for sending out mail on a per user level ?

I've been wondering how that's going to play out, myself. The first thing I'd expect ISPs to do is establish an egress filter to disallow connections to SMTP servers other than their own, entirely. Remote SMTP servers would probably only be usable if they're available on port 465 (SSL) or 587 (MSA), or via VPN.

There are a couple of ways to limit mail through your own system. There's a "ratelimit" filter in my pythonfilter package that limits the number of messages per IP, for instance. :)
