Our blog shares expert insights on email security, DMARC configuration, and deliverability optimization.
Publishing SPF, DKIM, and DMARC records is just the start. Without monitoring, you won't know when authentication breaks, new senders appear, or someone starts spoofing you.
We're sponsoring VPSArmor.com to raise the awareness on the topic of security for self-hosters.
Forums show the same anxiety pattern: 'I want p=reject, but I'm afraid I'll block legit mail.' The rollout is mostly about gates: inventory done, alignment fixed, SPF lookup limit avoided, and then staged enforcement.
The biggest practical blocker to moving beyond p=none isn't DNS syntax. It's discovering every legitimate sender. DMARC reports expose these "unknown senders" and Shadow IT that you didn't even know existed.
