Spammers Forging Our E-Dress

Hey Ya'll -

Is there ANYTHING I can do to stop spammers from using our email address in the "from" field? I've setup a SPF record for our domain. Also, they are NOT relaying or sending through our server - just forging our address. As a result, we're getting thousands of "bounced emails". They are using "support@hppchristianhosting.com" as the "from/reply-to" address. Obviously, we are NOT sending these emails.

Below is a sample header:
Hi. This is the qmail-send program at compuserv.compuservdns.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<nadinem@compuserv.net>:
Questo indirizzo non è stato accettato dal server.
