Is issy.com protected against email spoofing?

Not yet — issy.com only monitors DMARC (p=none); spoofed mail can still be delivered.

D

DMARC

p=none

SPF

?all

DKIM

1 selector(s)

Published record

v=DMARC1; p=none;rua=mailto:jean-paul.poggioli@ville-issy.fr;ruf=mailto:mosi@ville-issy.fr

What this means

  • Politique p=none : surveillance seule, aucun message non authentifié n'est bloqué.
  • SPF se termine par ?all (neutre) : n’apporte aucune protection effective.
  • 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.
