Daystar DNS Records

This document is provided for Daystar customers who manage their own domain and DNS settings. If Compass manages your email domain, we will ensure the correct records are in place.

1. MX record

Add an MX record with a priority of 10 pointing to mail.daystar.io. Any TTL value is acceptable, with one hour being common. Leave the "host" field blank or enter @ if required.

2. SPF record

Add a TXT record with the following value:

v=spf1 include:daystar.io ~all

Leave the host field blank. Use @ if your DNS provider does not allow for blank host names.

3. DKIM records

Add two CNAME records:

  1. Host of pmg._domainkey with a value of pmg._domainkey.daystar.io
  2. Host of dkim._domainkey with a value of dkim._domainkey.daystar.io

4. DMARC record

Domain-based Message Authentication Reporting and Conformance (DMARC) records are optional, but are recommended to prevent email spoofing on your domain.

Add a TXT record with a host of _dmarc and the following value:

v=DMARC1; p=quarantine; pct=100; rua=mailto:dmarcreports@compassfoundation.io; ruf=mailto:dmarcreports@compassfoundation.io

While the above settings will send DMARC reports to the Daystar administrators, you may use any DMARC reporting service available. To use a different DMARC reporting service, update the dmarcreports@compassfoundation.io address in the TXT record above to an email address of your choice.
