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.

COMMON QUESTIONS
MX Lookup FAQ
Practical answers from the HostGraber team.
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.
