Configuring DNS records correctly is vital for your domain’s functionality. In this guide, you’ll find the Spacemail DNS records you need and what each one does.
Hostname | Record type | Priority | Value |
|---|---|---|---|
@ | MX | 0 | |
@ | MX | 0 | |
@ | TXT | v=spf1 include:spf.spacemail.com ~all | |
spacemail._domainkey | TXT | the unique value should be copied from Advanced DNS in your Spaceship account | |
_dmarc | TXT | v=DMARC1; p=none; rua=mailto@yourdomain.com (or the one generated using an online DMARC generator tool, e.g. MXToolbox DMARC Record Generator) | |
_autodiscover._tcp | SRV | 0 | Weight: 0 Port: 443 Target: autoconfig.spacemail.com |
Note: @ represents your root domain (for example, yourdomain.com)
spacemail._domainkey represents spacemail._domainkey.yourdomain.com
Go to Advanced DNS and find your domain for Spacemail
Tap the arrow next to it and scroll to Inactive records
Expand the section and find Spacemail DNS records
Copy the record that starts with v=DKIM1; k=rsa; …
Add this record to your domain using the hostname spacemail._domainkey
Make sure the record is added at your DNS provider (the company that manages your domain’s nameservers).
Note: After adding the records, DNS changes usually take effect within a few hours, depending on the domain’s TTL settings. However, if the nameservers were changed as well, propagation may take up to 48 hours.
Modern email providers (including Microsoft Outlook, Hotmail, Gmail, and Yahoo) increasingly rely on DMARC as part of their sender reputation and anti-spam validation systems. Domains without a properly configured DMARC record are more likely to experience deliverability issues, spam folder placement, or reputation-based restrictions.
To configure DMARC, you will first need to generate a DMARC record using an online DMARC generator tool (for example, MXToolbox DMARC Record Generator) and then add it as a TXT record to your domain’s DNS zone.
NOTE: The DMARC policy can later be adjusted to quarantine or reject depending on your email setup and monitoring preferences.
MX records direct incoming emails for your domain to Spacemail servers. So that all emails are delivered to Spacemail.
SPF (TXT record) tells other mail providers which servers are allowed to send email for your domain. This helps prevent spam and fake emails.
DKIM (TXT record) adds a digital signature to your outgoing emails. This helps confirm that messages were sent from your domain and haven’t been altered in transit, improving email delivery.
DMARC (TXT record) helps protect your domain from email spoofing and phishing by defining how unauthorized emails should be handled.
SRV record helps email clients automatically find the correct mail server and connection settings when setting up an email account, reducing the need for manual configuration.
Note: If you’re using a third-party domain, make sure to add the TXT verification record first. This record confirms that you own the domain before you activate Spacemail or any other Spaceship service. If your domain isn’t verified, your Spacemail subscription won’t function properly because it won’t be actively connected to the domain. As a result, you won’t be able to log in to your mailbox or send emails. Additionally, the subscription may be disconnected later if the domain remains unverified.
