IPv6s are too cheap for most mailbox providers to take seriously. If someone sends spam, you need to block their IP, but they also need to lose money. Spammers don't care if they lose an IPv6. They'll just send spam from another.
(I don't really know what I'm talking about.)
- thayne 5y agoThat's where DKIM and SPF come in.
- ikiris 5y agoNot really. If you look at the numbers, spam almost always has these.
- corty 5y agoYes really. With DKIM, you blacklist domains, not IPs. Of course, only if you do it properly. Hotmail doesn't...
- Avamander 5y agoYou're pretending that domains aren't a cheap disposable commodity, they are.
- ATsch 5y agoThat's to be expected. All it does is ensure the accuracy of the email sender. Which finally lets you attach reputation to domains instead of addresses.
- ikiris 5y agoNo, I mean its to the point that mail with this signature is almost always (multiple 9s) spam.
- thayne 5y agoBecause most email providers will block you if yo don't have them now. And because of that, if you get blacklisted you need to buy a new domain, not just a new ip address.
