    I think this discussion on mail servers running on DSL/Cable static
IP connections are far beyond from RFC scope discussions.

    Those people, who chooses to run their mailserver on DSL/cable
connections and NOT relay on their ISPs are already having bad times
when sending mail to big ISPs and big companies.

    Even it's 'OK' on RFC scope, this is not OK on the real world
anymore. The real world seems to be completly happy with some
false-positive rejections when these dynamic-ip rules do block MILLIONS
of bad messages.

    I had some mailservers running on static IP DSL lines here in Brazil
and tried, for some time, to avoid upstreaming the messages to the ISPs.
But .... for more than a year now, i realized that that was a lost war.
And i started upstreaming messages to ISPs. Received messages comes
directly to my static IP DSL lines, but outgoing messages goes to the
ISP mailservers.
