2 selector(s)

Published record

v=DMARC1; p=quarantine; sp=quarantine; pct=100; rua=mailto:dmarc.notifications@shawbrook.co.uk; ruf=mailto:dmarc.failures@shawbrook.co.uk; fo=1

What this means

• Politique p=quarantine : les messages non alignés sont mis en indésirable.
• SPF se termine par ~all (softfail) : acceptable en phase d’observation, viser -all à terme.
• Au moins une clé DKIM valide publiée.

How to fix it

Marc, the DMARC copilot, finds every sender, writes the exact DNS, and walks your domain safely from p=none to p=reject.
