Technical configuration changes and service cancellation may not occur at the same time. If you plan to change your MX record to other server(s) from Email Security.cloud before scheduled cancellation date, you may require a few changes in our service configuration since Email Security.cloud has a different mail routing between our customers.
Before making change in MX record:
Update Inbound Routes to new MX record hostname before changing current MX record if you plan to receive all inbound mails in new MX record.
Make sure to keep Email Security.cloud SPF record until your domain(s) has fully been removed from Email Security.cloud: "include:spf.messagelabs.com".
When to change MX record:
Once the change in Inbound Route has been propagated, you may change the MX record. It may take up to an hour for the changes to get fully propagated.
After the change:
After TTL of the new MX record expires, you may remove the domain(s) from Email Security.cloud. If you keep your domain(s) provisioned, you may need to keep updating Address Registration until cancellation date. Please note that all reports and logs will be deleted once your domain(s) has been removed from Email Security.cloud.
