Step 1. Check you or your colleagues didn't blacklist the sender or their domain - in your Admin Panel, go to Filtering -> Blacklist page and search for the domain of your sender.
Step 2. You can by-pass their faulty configuration but you should be very careful as you'll expose yourself to fake emails. Use this guide to whitelist the sender - careful, you're doing this at your own risk. The best approach would be to advise the sender to fix their issues.
