Made the switch to self-hosted https://mailu.io (on k8s) 2 years ago when Gandi announced the deprecation of their free plan. Happy after IP was off most blocklists, but setup was kinda rough - https://mxtoolbox.com is your friend. - Source: Hacker News / over 1 year ago
I used these tools in the past: https://mxtoolbox.com/ https://www.mail-tester.com/. - Source: Hacker News / over 2 years ago
Suprised to not see https://mxtoolbox.com in this list too. - Source: Hacker News / over 2 years ago

The curl above is the fastest check; all four lines should come back. In a browser, DevTools, Network tab, click the document request, read Response Headers. For a letter grade, securityheaders.com scores you against a known rubric. One quirk: these four alone land a B, and you reach A only once you add Content-Security-Policy. - Source: dev.to / 3 months ago
Remediation: Configure your web server to suppress or mask the Server header. Add security headers like Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options. You can use tools like securityheaders.com to check your current header posture. - Source: dev.to / 4 months ago
Step 4: Check your security headers (2 minutes) Visit securityheaders.com and enter your deployed URL. If you get anything below a B, you're missing critical protections. - Source: dev.to / 5 months ago
How to check: Run curl -I https://yourdomain.com and scan the response headers. Or paste your URL into securityheaders.com for a free graded report. - Source: dev.to / 5 months ago
