Other DNS providers
Cannot find your provider? First find where DNS is managed, then add the records from the table.
- Where to find it
- The DNS page run by your domain registrar or DNS host
Follow these steps
- Find where the domain's DNS is managed. In a terminal, run dig NS with your domain, or search your registrar's site for "DNS" or "Nameservers".
- Add the records from the table below on that page.
- Fill the host field as shown in the table. If the provider asks for the full name, use the full name from the table.
- Back in mailsi, press "Check".
Records to add
These records follow the same rules as the setup wizard in the app. MX is required. SPF, DKIM and DMARC are recommended. After you add the domain, mailsi shows your own MX value.
- Type
- MX
- Host
- @
- Value
- <your-unique-host>.mx.mailsi.dev
- Priority
- 10
- Purpose
- Inbound MX. This record alone proves you own the domain.
- Type
- TXTrecommended
- Host
- @
- Value
- v=spf1 include:spf.mailsi.dev ~all
- Purpose
- SPF: include spf.mailsi.dev so replies land in the inbox more often.
- Type
- CNAMErecommended
- Host
- mailsi1._domainkey
- Value
- mailsi1._domainkey.mailsi.dev
- Purpose
- DKIM CNAME: on Cloudflare set it to DNS only (grey cloud).
- Type
- TXTrecommended
- Host
- _dmarc
- Value
- v=DMARC1; p=none
- Purpose
- DMARC: no policy exists yet; start with p=none to monitor.
<your-unique-host>.mx.mailsi.dev is a placeholder. Your real value is unique and appears in mailsi after you add the domain.
Common mistakes
- Remove old MX records. If the domain pointed at another mail service, leftover MX records can send mail there.
- Only one SPF record is allowed. If you already have a v=spf1 TXT record, add include:spf.mailsi.dev to it instead of creating a second record.
- Keep the DKIM CNAME as DNS only (grey cloud) if your provider is Cloudflare.
- The default TTL from your provider is fine, for example 300 seconds or one hour.
- DNS changes can take minutes to hours. mailsi checks automatically and shows the result in the app.
- The MX record belongs on the domain itself (host @), not on www or another subdomain.
Add your domain first
Add the domain in mailsi to see your unique MX value and check each record.
