Came here to say the same, if you’ve not got SPF at least a lot of email handlers will reject, DMARC and DKIM are becoming more required.

Also “don’t pretend to have done something massive when you barely did anything”.
This is a DMARC/DKIM misconfig, and sending this dumb ass email is the most “rejected from Penn” way to exploit it

That domain was registered in Korea and has been out in "client hold." However that also means no DKIM, SPF, DMARC - so IF YOUR MAILSERVER IS MISCONFIGURED it can still be used as source of spoofed mail.
But if you are seeing that mail, you need to fix your mailserver.

Some of my emails were being blocked due to a DMARC failure related to a DKIM signature misalignment, but I successfully changed the DKIM configuration and my emails are now getting through.
Please clap.

Yeah the only things under your direct control would be DNS settings - SPF, DMARC, etc
Shared hosting: if you’re on Ghost Pro, that’s on them to manage.
If you want to DM / email I can take a (non expert) look.
FWIW - it reached my Fastmail inbox 📥

Most email marketers obsess over DKIM/DMARC/SPF.
But those only get you to the door.
Inbox placement is decided by engagement, not just authentication.

Looking a bit further seems to be a #DMARC issue. So the fact that a 3rd party sent my email meant it was blocked by *some* government email servers. That inconsistency is troubling. If it's a necessary policy ALL govt email should be responding similarly.

The “SMTP smuggling” security hole is causing unrest among postmasters before the holidays.
But: Our users at mailbox.org are protected. We are currently activating a config change that works around the problem. We also use DKIM/DMARC, which also protects us & you.
