It’s around 1pm on 3/23 - in the last 12 hours, I’ve recieved over 500 pieces of spam mail, all with identical Received from: headers:

What I’d like to be able to do is turn on (or turn off) the ability for someone to send email to any address at my domain - you’d have to have an actual address, you couldn’t just use [anything]@mydomain.com to get email through. I have Razor set up but it’s just not catching these.
I suspect this is a deliberate target as the addresses that are being spoofed as the return addresses come from a usenet newsgroup I frequent.
Any help or advice welcomed.
