Scanning your domain…
Checking SPF, DMARC, DKIM, MX, DNS, blacklists and domain & SSL expiry. A domain we haven't scanned before takes a few seconds — hang tight.

Solid base — two policy steps remain.
dylan-kerr.net publishes DMARC with p=none — spoofed mail is monitored but not blocked.
Your SPF check is using a softer “maybe not allowed” setting for mail that isn’t listed, instead of a stricter “block it” setting. This matters because it can make spoofed or misconfigured emails a little less clearly rejected by other mail servers. The fix is to switch to the stricter setting only after you’re sure every legitimate sender is already included in your SPF setup.
v=spf1 include:_spf.google. DMARC is set up, but it is only in monitoring mode, so it is not actively blocking spoofed or fake emails from your domain. This matters because attackers can still try to send mail that looks like it came from you, which can hurt trust and deliverability. The fix is to change DMARC from monitoring-only to an enforcement policy so mail that fails checks is handled instead of just reported.
