Hello @TheITGuy ,
The error message that you are receiving is generated due to the fact that either the email address, server's IP, or domain are added to the Spam Deny list. More precisely either the gmail address, the whole gmail domain or the server IP which is sending the email are added to the Spam Deny list.
You can consult the following article which details the steps on how to check the Spam Deny list and remove the entries related to gmail that you consider: https://www.bitdefender.com/business/support/en/77211-491964-receiving-the--550-5-1-8-sender-denied--error-for-inbound-or-outbound-emails.html
If you are still need assistance you can open a case with our Enterprise Support Team as mentioned by @Flexx and we can impersonate your account (with your approval) and review your configs.
Kind Regards,
