Cable modem users don't need the IPS's servers for outgoing
email. They have the "always on" connection needed to
reliably deliver email. The only reason email went via
ISP's servers back in the dialup days was to get reliable
delivery.
In the US there is even more insentive to bypass the ISP's
servers. Look are the way they have interpreted the wire
tap laws.
Sane end users would also be configuring there systems to
detect interception of email. Crypto was added to SMTP
for a reason. ISP's shouldn't be getting in the way of
using it.
