MX Lookup
Find the mail exchanger records published for a domain and their delivery priority.
What this result means
MX records identify mail exchangers. Lower priority numbers are preferred, but an MX record alone does not prove email delivery is working.
How this check works
Multiple MX records can provide redundancy and routing choices. Delivery also depends on SMTP configuration, reputation, and email-authentication policies.
