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

Thanks for your response Gordon.

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.

What if all clients can only use SMTP ports after authenticating, and perhaps only then via SSL (465), would such egress filtering still be required ?

There are a couple of ways to limit mail through your own system.

And aside from your suggestion below ?

There's a "ratelimit" filter in my pythonfilter package that limits the number of messages per IP, for instance. :)

A single user is probably locked to a single IP so that would be good enough to work with. URL please ? Any docs ?

So I take there is no native built-in support for courier-mta to handle outgoing rate limits ?
