Although it won't stop the spammer from using your domain.... if you
had a SPF record on your company domain, then legit servers would more
than likely not accept the spammer's email, and thus there would be
fewer bounces back to you.

I see that you use Google Apps for your company email, assuming that
you don't operate any other internal company mail systems, you can
accomplish this by adding a DNS TXT record with the following data:

     v=spf1 include:aspmx.googlemail.com -all
