UNDERSTAND THE TOOL

What is MX Lookup?

MX records direct incoming email to one or more mail servers. Priority values determine which server should be attempted first.

Verify MX records after changing email providers or when a domain cannot receive mail.

READ THE OUTPUT

How to understand your results

Three signals that matter most when interpreting this tool.

01

Priority order

Lower MX preference values are attempted first; higher values provide fallback routing.

02

Mail hostname

Each MX target must be a hostname that resolves to a reachable mail server.

03

Provider consistency

All displayed MX records should belong to the mail platform you currently use.

HOSTGRABER EXPERT GUIDE

Tracing the complete email delivery route

MX records identify where the internet should deliver inbound mail. Each target must be a hostname—not an IP address—and that hostname needs a valid address record. Preference values are evaluated from lowest to highest, allowing providers to operate primary and fallback receivers.

Before switching to HostGraber Business Email, inventory the existing MX, SPF, DKIM and DMARC records. Publishing only the new MX records may restore incoming mail while leaving outgoing authentication broken. Validate the full email DNS set as one migration checklist.

PRACTICAL GUIDE

Getting a reliable answer from this tool

Domain, DNS and IP checks are most useful when records are reviewed together. A website can resolve correctly while mail, reverse DNS or a secondary hostname is still misconfigured. Use this result alongside authoritative nameserver checks and allow for DNS caching whenever records were changed recently.

For migrations, document the current state before editing anything. Compare the old and new answers, confirm the expected destination and keep unrelated records such as email authentication intact.

COMMON QUESTIONS

MX Lookup FAQ

Clear answers for common mx lookup questions.

Can an MX record point to an IP address?+

No. An MX target must be a hostname with its own A or AAAA record.

Why are there multiple MX records?+

Multiple records provide load distribution or backup delivery when the primary mail server is unavailable.

Do I need MX records to send email?+

MX is primarily for receiving mail. Sending also depends on SPF, DKIM, DMARC and the outbound mail server configuration.
