SMTP Relay configuration in full hybrid environment
Hello, I have a question regarding the configuration of the SMTP Relay in Full Hybrid environment. My infrastructure is full hybrid with a 2016 exchange server on premise. We also utilize a Barrauda ...
Yes when creating/viewing the connector in the Admin Center it is complaining about the DNS record. It always expects to see yourdomain-com.mail.protection.outlook.com but our MX records contain the smarthost data instead. I expect M365 has no way to detect a defense gateway in front of thier services. Our autodiscover record is also not what is expected it is looking for autodiscover.outlook.com and we are still pointed at our domain.
Can you describe what options did you choose to create the connector? or add a screenshot, hiding any private info.
- Current testing has been primary using the existing hybrid connectors for sending from on-prem to Exchange online. That connector is certificate based. I have created a new connector that uses the IP option where our external IP('s) for our firewall are listed. I will test this way and see how I get along my understanding is the IP method would be better for eliminating the possiblity for scanned email to be flagged as spam. The question still remains what do I list for the server address if I am setting up a copier for a scan to email function? I assume yourdomain-com.mail.protection.outlook.com is still appropiate though it does not match the MX record. What rules should be created to make sure the scanning device uses the desired connector?
- You should be able to set yourdomain-com.mail.protection.outlook.com in your device as destination to send your email.
Is the device using a static IP Address? did you update your SPF record to add it?
