I am working with a company whose employees are finding that their emails to a number of Proofpoint protected recipients are never arriving. There is no bounce or error, and in almost every case the recipient doesn't receive anything (in one case a recipient found the email in a spam quarantine/junk folder). I'm trying to help them identify any problems and correct them in order to deliver properly. They are sending from Microsoft 365, and the IPs I have looked up are all clean on Proofpoint's list, so I believe it is a domain reputation issue rather than network.
The only public-facing reporting form I can find is https://ipcheck.proofpoint.com/ for IP address issues. Can anyone point me to a public-facing form for domain issues? (or anything other than IP) If there is a Proofpoint person who might take a look, I'd certainly appreciate that also! I'm happy to provide the domain and other details directly. Thank you!
