The trick is not to block the domain of the email address, those are forged anyway. The trick is to block the domain of the IP that the email came from. I'm building a pseudo-mini-DNS to do this that comprises a regex of the full range of IPs for that domain, a username for the abuse address (bfore the "@"), and the domain itself (after the "@")...
Eventually I wanted this system to return the favor by auto-spamming their abuse address with a forward of each one I get. That kind of backfired, since there are truly foul email servers that collect received emails to... you can guess the rest.
That's how I knew Comcast was hacked to do that some time back. I was getting ten+ back for every one I sent. You can see how that escalates exponentially if I'm "returning the favor".

I have no clue how to do any of that, so, for the interim, the best I can do is block the domain and hope for the best. Again, though, due to Outlook having a great spam filter, it doesn't really affect me any more than being an annoyance.

For all I know they do that, but I can tell you that 90% of the spam you get comes from only a handful of server domains.

All the spam is coming from <random>@<random>.nelottery.com
Since the parameter after the "@" appears to be randomly generated, I don't know how to shut it out. Outlook, indeed, is sweeping all of these to the Junk Folder, but boy, I would love to be able to get to Hughes so that THEIR master spam blocker would stop these in their tracks.
And, it is totally possible that nothing can do this. I am SOOOOO darned careful online, so I get really pissed when someone gets my email address and either spams me or spoofs me.
I'll have to see if I can find the IP addresses - but I don't know how to filter those, unfortunately.

*.nelottery.com? Sounds like one I haven't seen yet.
Chances are that someone that does have your email address got their address book lifted. The only way to ensure that doesn't happen is not to use email at all, and that kind of defeats the purpose of having it.
Only thing you can realistically do to stop it, and have some control over it, is the kind of system I'm currently setting up (why I'm doing it actually). This is after tons of research on the subject.
