I've seen an increase in backscatter emails recently. Perfectly valid
headers (AFAICT)

But the message they are bouncing is not mine:

(I did just update this spf record to "v=spf1 a mx
ip4:75.148.117.94/29 ~all" which I expect will help some)
Is there some sort of strategy I can implement that will reject a good
portion of these kinds of messages? What are other people doing to
deal with backscatter? I read up on SRS, but it doesn't sound like a
great idea.
