Short answer
DMARC ties SPF and DKIM together: it tells receiving servers what to do when a message claiming to be from your domain fails those checks, and where to send reports. Start with a monitoring-only policy, read the reports, then tighten it.
This is a general web-hosting explanation, not specific to Traxio.
A sensible first DMARC record is v=DMARC1; p=none; rua=mailto:you@yourdomain.com. That changes nothing about delivery but starts the reports flowing, so you can see who is sending as your domain before you move to p=quarantine or p=reject.
