nobody blacklists email addresses !!

Exactly this is what is done.
Find spam friendly/misconfigured Mailservers, and block them.
there are a dozen services which can be queried via a DNS interface.

Actually they block IMHO mail from these domains, if they are NOT originating
from the domain's Mailserver.
gmx.net does this as well.
This partly works, because many spammers use @yahoo.com or @hotmail.com fake
addresses, and naturally NOT use the Mailservers of these domains.
