Dynadot

Use this guide if your domain uses Dynadot DNS, with nameservers such as ns1.dyna-ns.net. Every Notix record goes on a subdomain, so they all go in the Subdomain Record (optional) part of Dynadot's DNS settings.

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 Dynadot

1. 1

   Open DNS Settings

   Sign in and go to My Domains, then Manage Domains. Tick your domain, open the Action menu and choose DNS Settings. Make sure Dynadot DNS is selected.

2. 2

   Add each TXT record

   In the Subdomain Record (optional) part, use an empty row:

   1. In Subdomain, enter the name from the table, for example _dmarc.
   2. Set Record Type to TXT.
   3. In IP Address / Destination, paste the value, without quotes.

   Use one row each for the DKIM, SPF and DMARC records.

3. 3

   Add the MX record and save

   In another subdomain row:

   1. In Subdomain, enter mail.
   2. Set Record Type to MX.
   3. In IP Address / Destination, paste the MX value, for example feedback-smtp.eu-west-1.amazonses.com.
   4. In Priority, enter 10.

   Press Save Settings to save all the rows.

Things to know at Dynadot

• Do not put the Notix records under Domain Record. That part is for your main domain, the @ records. Dynadot says not to type @ itself.
• In Subdomain, enter only the part before your domain. Dynadot says so: if a name contains your domain, enter only the prefix.
• Dynadot asks you to remove quotation marks from TXT values.
• Dynadot's help pages do not mention a TTL field.

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

Dynadot only says a change might take some time. 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.
