1 TopicUnexpected Email Routing to Lower-Priority MX Record
We currently have two MX records configured in our public DNS: Primary MX Record: Priority 10 (EOP) Secondary MX Record: Priority 50 (retained temporarily) Despite the lower priority (higher numerical value) of the secondary MX record, we’ve observed instances of email traffic being routed to the priority 50 record. Could you help clarify why this might occur? Specifically: Are there scenarios where a higher-priority MX record (10) might be bypassed in favor of a lower-priority record (50)? Could this indicate misconfiguration, DNS propagation delays, or server availability issues? We aim to ensure proper email delivery to the intended priority 10 endpoint and would appreciate guidance on resolving this discrepancy.Solved83Views0likes2Comments
