Cloudflare

Use this guide if your domain's nameservers end in ns.cloudflare.com. If Notix offers Set up automatically on your domain page, use that instead: you approve the change at Cloudflare and the records are added for you. This guide is for adding them by hand.

The records to add

These names are for a domain added as acme.com. Notix shows each name in the short form, without your main domain on the end, so copy it from your domain page as it is. If you added a subdomain such as news.acme.com, the names read mail.news and notix._domainkey.news; _dmarc stays the same. The DKIM name and key are different for every domain. The MX value names the region your domain sends from, for example feedback-smtp.eu-west-1.amazonses.com, so copy it from your domain page too.

Add them at Cloudflare

1. 1

   Open DNS Records

   Log in to the Cloudflare dashboard, pick your domain and go to the DNS Records page.

2. 2

   Select Add record and choose TXT as the Type.

   1. In Name, enter the name from the table, for example _dmarc.
   2. In Content, paste the value.
   3. Leave TTL on Auto.
   4. Select Save.

   Repeat for the DKIM, SPF and DMARC records.

3. 3

   Add the MX record

   Select Add record and choose MX.

   1. In Name, enter mail.

   3. In Priority, enter 10.
   4. Select Save.

Things to know at Cloudflare

• Cloudflare uses @ for your main domain and a plain label such as mail for anything under it. Enter the short names from the table.
• The orange-cloud proxy does not matter here. Cloudflare only proxies A, AAAA and CNAME records; TXT and MX records are always DNS only.
• If you paste a TXT value without quotes, Cloudflare adds them for you. That is fine.
• Cloudflare also offers its own DMARC wizard under Email, DMARC Management. If you use it, do not add the Notix _dmarc record as well.
• If a hosting company added your domain to Cloudflare for you, Cloudflare says to manage the records through that company.

SPF and DMARC: check before you add

• SPF. A name can have only one SPF record. Notix puts its SPF on mail, not on your main domain, so it never clashes with the SPF your main domain may already have for your mailbox provider. Leave that one as it is. If mail itself already has a TXT record that starts with v=spf1, do not add a second one: edit it to include include:_spf.usenotix.dev.
• DMARC. A domain can have only one DMARC record. If _dmarc already has a record that starts with v=DMARC1, keep it and skip the Notix one. Notix accepts the record you have. Two DMARC records cancel each other out, and mailbox providers then ignore both.
• MX on `mail`. The MX record only takes bounce and complaint reports back to Notix. It does not touch the MX records on your main domain, so your normal inbox keeps working.

After you save

A TTL of Auto is 5 minutes at Cloudflare, so changes usually show quickly. Most records show in Notix within about 10 minutes.

You do not need to watch the page. Notix checks your records again on its own, and the domain turns Verified when the required records are found. To check straight away, open the domain in Domains and press Verify again. If a record is found at the wrong name, for example mail.acme.com.acme.com, the domain page says what to fix.

The records you add stay at your DNS host. Do not delete them later: Notix keeps checking them while you send.
