When email stops after a nameserver move, first check the records served by the new authoritative DNS host. Missing or incorrect MX records can affect incoming mail; missing sender-authentication records can affect outgoing messages. Also confirm the mailbox service itself is still active.
Before you begin
- Determine whether receiving, sending or sign-in fails.
- Check the authoritative zone, not an inactive copy.
- Keep the mailbox subscription in view.
Identify which direction fails
Send a message to the affected address from an independent mailbox and try a reply. Record any bounce message and whether users can still sign in to webmail. Receiving, sending and account access are different symptoms with different likely causes.
If webmail works but new messages do not arrive, incoming routing deserves attention. If incoming mail works but a website’s receipts fail, investigate that sending service and its authentication. Avoid changing every record before you know which path is broken.
Inspect the new active zone
Confirm the domain’s current nameservers, then compare the new zone with the saved settings from before the move. Check MX destinations and priorities first for incoming mail. The old DNS editor may still show perfect records that are no longer being used.
Check SPF, DKIM selectors, DMARC and any mail-related hostnames or verification records required by the provider. A zone import may not have captured every entry, especially if the old configuration was recorded only through public lookups.
Restore the missing configuration deliberately
Use values from the actual email provider and keep a record of what you change.
- Confirm the mailbox subscription and recipient accounts still exist.
- Restore the required records at the authoritative DNS host.
- Check for competing old MX routes.
- Validate sender authentication for the services you use.
- Test incoming and outgoing mail again and keep any remaining error details.
Do not confuse routing with message migration
Changing nameservers does not move old inbox contents to another host. If the old email subscription was cancelled during the move, restoring DNS alone may not restore access to those messages. Contact the email provider about the account and any available recovery route.
Once service is stable, update the domain inventory and keep a complete zone backup for the next move. The domain can remain registered at NameUK while DNS and email are elsewhere; renew each service according to its own schedule.
