FAQ
What are MX records?
They define which servers receive inbound email for a domain and their priority order.
Do I need MX records?
Only if you want to receive email on this domain. Sending can work without MX depending on provider.
Why is Exchange shown as “.”?
Some configurations use a null MX (RFC 7505) to explicitly disable email receiving.
Should I have multiple MX servers?
Usually yes for redundancy, unless your provider explicitly uses one.
How long does DNS change take?
Propagation depends on TTL and caching; typically minutes to hours.
Common mistakes
- MX points to a hostname without an A/AAAA record.
- Using CNAME for MX target (not recommended).
- Wrong priorities or only one server without redundancy.
