We have the Gmail -> Safety -> Spoofing and authentication -> Protect against spoofing of employee names setting set to ON and quarantine. Periodically, we send emails from our student information system from employees to groups of students. The domain of SIS is mail.veracross.com. Some of these emails, sent to students, are stopped in quarantine while others are not. There's no rhyme or reason to it.
I've added all emails addresses used by the SIS to communicate with students, as domain shared contacts. These email addresses now show up in user's contact lists. However, emails from our SIS are still being flagged as spoofing of employee names. After a bit of research, the reason why the domain shared contact method won't work in this scenario is because, while the email addresses stay the same, the From name does not.
We can't disable Gmail -> Safety -> Spoofing and authentication -> Protect against spoofing of employee names due to security concerns. This feature stops an incredible amount of bad actors trying to pose as our employees so it's critical that it be in use. However, there needs to be a way to instruct Google Workspace to allow all email from our SIS and not be subject to any type of filter.
I'd like to request a method, or whitelist perhaps, to override Gmail -> Safety -> Spoofing and authentication -> Protect against spoofing of employee names for certain email addresses.
