Findings
-
mx redundancy
Only one mail exchanger is published, so there is no failover.
asos-com.mail.protection.outlook.com
Fix: Add a secondary MX at a higher priority number.
-
mta sts
No MTA-STS policy, so inbound mail can be downgraded to an unencrypted connection.
Fix: Publish _mta-sts.asos.com and host a policy at https://mta-sts.asos.com/.well-known/mta-sts.txt.
