Allowing legimate email spoof?

We have a 3rd party mail system that does mass mailing (on behalf of our domain) to our patrons. Externally it works fine there are no problems. However the problem is if the 3rd party mail system sends an email to staff internally (using our .domain address) the email is blocked + bounced back to the sender (labelled as spoof). The problem is staff needs to see the actual sent email to see if the layout and newsletter is correctly configured. I believe there was a way to allow this but I can't remember how it was done. Do i need a SPF or DKIM entry in our TXT record in DNS for the 3rd party domain?

We are running a Barracuda Spam firewall appliance at the border for emails. So I believe it is being block at that point as the soft bounce message that the sender receives shows the DNS name of the barracuda appliance. However what's weird is that the email didn't even make it into the appliance and the appliance has no record of blocking the 'spoofed' emails.

Would the sender be providing me the info for the SPF and DKIM?
