MX records direct incoming email to the correct mail server. A lower priority number takes precedence over a higher number.
Which value should you enter?
| Record type | MX |
| Value | Mail server plus priority, for example 10 mail.example.com |
| TTL | Use the default value unless a provider specifies otherwise. |
What should you consider?
- Always use a host name as the destination, not an IP address.
- Make sure the destination host name itself has a valid A or AAAA record.
- Remove old MX records when they are no longer used.
DNS changes take time
After saving, an old value may temporarily remain in cache. Therefore, check not only in your browser but also with an external DNS checker.
Frequently asked questions
When will a change to MX become visible?
This depends on the TTL and provider caches. The change is often visible within a few minutes, but old responses may be retained for longer.
Can I undo a DNS change?
Yes. Restore the previous value and save again. This correction may also temporarily be affected by DNS cache.
Do I need to change the TTL?
Usually not. For a planned migration, you can lower the TTL in advance so later changes are retrieved more quickly.
