I take back everything bad I said or hinted at in the previous post.
Seems that when your $ORIGIN is .com, and your MX record is
MX 10 mail.xdroop.com
...the internet obediently tries to send mail to mail.xdroop.com.com, even though it doesn't exist.
I can't believe I missed that.
Literally fifteen seconds after fixing that and pushing it, the spam is flowing again.
So that means everything bad that's happened during my stay with Tera-Byte has been my fault. They have been a perfect host during my stay -- I never had to think about them or worry about them. And I think I got good value during my stay too.
