Thank you for the screenshot, it has been really helpful.
I was checking the email address that has been rejected, and based on this external page there is a problem with the email.
It seems to be related to the sending mail server is subjected to Greylisting. This requires the server retries the connection, between one minute and 12 hours. Alternatively, the sender's IP address has a poor reputation.
I would recommend to reach out your IT Team and do a whitelist the IP address HubSpot uses to connect your inbox. You can find more information here.
I hope this helps.
Thank you
