Don't think that's needed, if ISP's only allow outgoing SMTP to the ISP's

Does it really have to be funneled through their SMTP servers? Would it not
be sufficient simply to add a connection-level SYN throttle on that port at
the routers? Perhaps someone here could propose a set of iptables rules
that would implement this. Or the equivalent rule for a Cisco.
