Domain and DNS
A, MX, SPF, DKIM, DMARC, and reverse DNS records for your mail server.
Three setup steps
On the service page, the Finish your mail setup section has three steps. Email does not work correctly until they are complete.
1. Add DNS records
Create these two records at your DNS provider:
| Type | Name | Value |
|---|---|---|
A | mail.example.com | Server IP |
MX | example.com | mail.example.com with priority 10 |
- The A record points the mail hostname to the server IP.
- The MX record tells other servers where to deliver mail for your domain.
DNS changes usually take a few minutes, though in rare cases they can take longer.
If you use Cloudflare or a similar provider, set the A record for the mail hostname to DNS only. Proxying does not work for email.
2. Turn on SPF, DKIM, and DMARC
- Click Open admin panel. This link works after the A record is live.
- In the panel, open Mail domains.
- Click the details icon next to your domain.
- Click Regenerate keys.
- Add the SPF, DKIM, and DMARC records shown on that page to your DNS provider.
These records prove your email is legitimate and help keep it out of spam folders.
3. Set reverse DNS (PTR)
Ask support to point the reverse DNS (PTR) of the server IP to the mail hostname:
- Click Open a support ticket.
- Include the server IP and the mail hostname.
- Ask for the reverse DNS (PTR) record to be set.
Mail servers without a matching PTR record are often treated as spam by other providers.
Final check
After the records are in place, send an email from an external address to one of your mailboxes. If it does not arrive, see Troubleshooting.
