It's not entirely daft.  While I don't believe that ISPs should be
responsible for the inbound SPAM received by their customers, taking
steps to reduce outbound SPAM is reasonable:

"Under the new code, ISPs will have to [...] provide a system of
  handling complaints."

If this means providing a working a b u s e @ d o m a i n then it's merely
re-enforcing RFC 2142.

"They will also have to impose reasonable limits on the rate at which
  subscribers can send email."

This is similarly reasonable.  Given that 99.9% of home users should
legitimately only be sending mail:

a) via the ISPs mail servers, and
b) would send on average dozens (at most hundreds) of messages per day,

surely it makes sense to make the default policy for those users match
those assumptions: limiting port 25 outbound to just your mail servers,
and implementing outbound quotas on your mail servers.

The average customer won't notice these restrictions at all, and it
reduces the amount of SPAM proxied through those customer PCs which are
infected by viruses considerably.

For that 0.1% of customers for which this is a problem, ensure that you
provide an opt-out facility.
