"Like many people I still have a few email addresses in domains that I used in the past. Mail for those addresses is forwarded to my current address.

From what I understand he is rejecting backscatter that is sent to some of his old addresses (with an identical forged sender, but this is irrelevant) and from there forwarded to his mail server.
No... you're reading it wrong.
He is talking about domains of HIS... so he CONTROLS them... in other words, the same server that is receiving the backscatter is the one rejecting the forged backscatter.
You would be right if you were talking about an old hotmail account or something like that, but we're not.
