If not, setting one up may well help. Some time back I started getting a lot of backscatter due to some spammer forging my address as a spam sender. I set up an SPF record and back scatter tailed off rather quickly. May be I was lucky, but it certainly worked for me. However, it most be set up right: I used the wizard at http://www.openspf.org/ to create it and the testing tools at http://www.kitterman.com/spf/validate.html to validate the result, which was initially wrong. SPF had no impact on backscatter until the Kitterman validation tools passed my setup as correct.
