Hi,
We have a user on our team not being able to receive emails from the login flow, specifically 2FA emails to verify his identity when trying to login. Checked the Project email audit in Project Settings and seems like emails to this user is getting bounced with this message
Error from email provider: 554 5.4.7 [internal] message timeout (exceeded max time, last transfail: 421 4.4.0 [internal] no mail servers for this domain could be reached at this time)
I do not seem to have access to unblock this user from Project settings.
