Are they just "spoofing" the "From Address" or are they able to send out email from your domain? Two different things to discuss here.

Nothing you can really do other than educate your customers on how the From address can be spoofed by anyone. As long as you have SPF in place and you have other bases covered like not allowing SMTP Relay, you should be fine. I say "should be" because email these days is best left for the Professionals.

no, no spf has been setup, I guess that's a good start and I'll look into the smtp relay as well,

You might also want to disable your catch all account. It will save you from having to deal with all the bounce backs and genuine people wanting to contact you will use either your site forms or any address you gave them any way.
