We have a company who is currently doing e-mail scanning for us to block junk, virus & other unwanted mails.
We have decided to stop the service and rather go for our own in house solution. The problem I am facing is that all e-mails from above company are forwarded to owa.ourcompany.com However when check our exchange server I cannot see this MX record.
Do I have to wait until the service is stopped and then create the MX Record on our exchange server? Or can I safely assume that we will continue to send and receive e-mails without any changes required on our side?
Please advise
