Spaceship

Use this guide if your domain's nameservers end in spaceship.net, such as launch1.spaceship.net. You add three TXT records and one MX record in Spaceship's Advanced DNS.

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 Spaceship

1. 1

   Open Advanced DNS

   In Spaceship, open Advanced DNS and click the arrow next to your domain. Go to the custom records.

2. 2

   Add each TXT record

   Click Add record and choose TXT.

   1. In Host, enter the name from the table, for example _dmarc.
   2. In Value, paste the value.
   3. Leave TTL as it is.
   4. Click Add.

   Repeat for the DKIM, SPF and DMARC records.

3. 3

   Add the MX record

   Click Add record and choose MX. Enter mail as the host, paste the MX value as the mail server, set the priority to 10, and click Add. Spaceship's help pages do not name the MX fields, so the labels on your screen may differ.

Things to know at Spaceship

• Spaceship's own DMARC example uses _dmarc as the Host, with the domain shown beside the field. So enter the short names from the table, such as mail.
• MX is in the Add record list, but we could not find a Spaceship page that walks through MX fields. If the screen is unclear, ask Spaceship support where the priority goes.

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

Spaceship says changes to records usually spread within minutes to a few hours, and can take up to 48 hours. 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.
