[SLL] back scatter?

[billw at onedrous.org]

Spam on my mail host shot up recently with undeliverable mail, mail sent
with my email address on the from: line, but, of course, not sent by me.

I was reading freedom-to-tinker.com yesterday and learned that the
phenomenon is known as backscatter, and that there are good plugins that
will drop bounces if they didn't originate on my mta.

How are folks on this list dealing with this problem?

Thanks,

 -Bill
