Step by step in Hostinger
Verify your domain
Your email provider needs proof that you control this domain before it accepts email for it.
- Type
- TXT
- Name
-
@ - TXT value
- Copy it from Proton Mail settings (Domain names) (see below)
Where to find your value
In Proton Mail open Settings → Domain names, add your domain and copy the verification value.
It looks like: protonmail-verification= followed by a code
In Hostinger
- In Manage DNS records, choose TXT as the type.
- Enter the Name (@ for the root, or only the prefix such as _dmarc) and the TXT value.
- Click Add Record.
Point your MX records
MX records tell every other mail server where to deliver email for your domain. They must point to your provider and nowhere else.
- Type
- MX
- Name
-
@ - Priority
- 10
- Mail server
-
mail.protonmail.ch
- Delete any other MX records, or make sure Proton's have the lowest priority number.
- Type
- MX
- Name
-
@ - Priority
- 20
- Mail server
-
mailsec.protonmail.ch
In Hostinger
- In Manage DNS records, choose MX as the type.
- Enter @ as the Name, your provider's mail server, and the Priority. Keep the default TTL unless your provider asks otherwise.
- Click Add Record.
- Repeat for each MX record above.
Add the SPF record
SPF is a TXT record that lists the services allowed to send email from your domain, so receivers can spot forgeries.
- Type
- TXT
- Name
-
@ - TXT value
-
v=spf1 include:_spf.protonmail.ch ~all
- Keep one SPF record. To keep an existing one, add include:_spf.protonmail.ch right after v=spf1.
In Hostinger
- In Manage DNS records, choose TXT as the type.
- Enter the Name (@ for the root, or only the prefix such as _dmarc) and the TXT value.
- Click Add Record.
Set up DKIM
DKIM publishes a public key so receivers can confirm your messages really came from you and were not changed on the way.
- Type
- CNAME
- Name
-
protonmail._domainkey - Content
- Copy it from Proton Mail settings (Domain names) (see below)
Where to find your value
Copy the exact target from the DKIM tab of your domain in Proton Mail settings.
- Add all three DKIM records; Proton rotates keys between them.
- Some hosts reject a trailing period on CNAME values. If yours does, remove the final dot.
- Type
- CNAME
- Name
-
protonmail2._domainkey - Content
- Copy it from Proton Mail settings (Domain names) (see below)
Where to find your value
Copy the exact target from the DKIM tab of your domain in Proton Mail settings.
- Type
- CNAME
- Name
-
protonmail3._domainkey - Content
- Copy it from Proton Mail settings (Domain names) (see below)
Where to find your value
Copy the exact target from the DKIM tab of your domain in Proton Mail settings.
In Hostinger
- In Manage DNS records, choose CNAME as the type.
- Enter the name (only the prefix) and the content your provider gives you.
- Click Add Record.
- Repeat for each CNAME record above.
Add the DMARC record (recommended)
DMARC tells receivers what to do with mail that fails SPF and DKIM, and where to send reports about it.
- Type
- TXT
- Name
-
_dmarc - TXT value
-
v=DMARC1; p=quarantine
- Proton recommends a p=quarantine policy for most domains.
In Hostinger
- In Manage DNS records, choose TXT as the type.
- Enter the Name (@ for the root, or only the prefix such as _dmarc) and the TXT value.
- Click Add Record.
Check your setup
Once the records are saved, run a live check. We look up your domain in public DNS and tell you what is right, missing or wrong, with the fix in Hostinger’s words.
