I wonder how many years it will take for them to expire from all
blocking lists in the world.

I don't consider it dictate. Any ordinary dialup customers must be
interested in getting rid of his outgoing mail as fast as
possible, which is done by delivering it to the ISP's mail host
and let it do the hard work with slow and deferred transfers.
That way the customers save phone costs and time.

As a side effect it may be easier for the ISP to track it's spammers.

If the customers are concerned about privacy, they should use
encryption anyway.

Nice, but not very complete. Thanks. It does not solve the
problem that I have to remember at regular intervals to check
that those ip's still are used for dialups.
