Salesforce Emails Not Received By Mimecast

Hi All,

We are facing an issue where we have stopped receiving emails from salesforce altogether. We are using mimecast for email security filters and as per them they are not receiving any requests from salesforce so there is no error in the logs. Even the 'Test Deliverability' is not working. We have checked the IP whitelist and salesforce IPs are listed under that. Has anyone faced this issue or if you have any inputs please put it in the comments.

Thanks
