- 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.
