Is it possible to run a local smtp server without using the smarthost of
your provider by dynamic IP. Then it's easy to spam around. So I
understand the reason why those IPs are blacklisted. Dynamic IP's aren't
static.

If it's a dynamic IP range and someone spams there, they will blacklist the
whole range. Blacklisting only one IP wouldn't solve the problem.

I remember a similar discussion in a longer thread here:

Use a smarthost for your mails and the sun will shine again.
