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.
