How to use MX Lookup
What if a domain has no MX record?
A domain without MX records may still receive mail at its address records. A single MX record of 0 followed by a dot is different: it explicitly says the domain does not accept email.
What should I check after changing providers?
Compare your preferred and backup routes against the new provider’s instructions. Then check published SPF and DMARC. DNS checks do not prove mail delivery or check a message’s DKIM signature.
