ISPs submit ther dynamic IP blocks to the Spamhaus Policy Block List as a matter of course (the PBL is a list of IP addresses for which the owners have said that as a matter of network policy will never originate E-Mail)

This is a win for the ISPs (it makes the blocks useless to spambots) and, to be honest, I can't see any reason why the situation would change.


As for E-Mail: I think half of the reason why setting up an E-Mail server is so scary because it's an essential service. If E-Mail goes wrong, we drop off the net.

As for myself: I setup and mostly configured my new VPS to handle E-Mail a month ago, but haven't cut over to it yet due to the difficulty of extracting all the mail from my GMail account. Now that Google have announced Google Takeout for GMail, that should be a lot easier (And thanks, Google, for demonstrating that you do still care about data portability)
