As far as I can tell, the major blacklist providers do not distinguish
between dial-up IPs, fluctuating dynamic IPs, and those that are
nominally dynamic but change rarely. They are all on the blacklist used
by JANET now.

Those entries would be based on evidence of guilt -- unlike the dynamic
IP blacklists.
A lot of mail administrators now are extremely arrogant about this
issue: they refuse to whitelist IPs or dyndns-like hostnames and argue
loudly that people who can't afford to pay for business internet
services have no business routing their own mail.
