Ghost sign up and spam?

[jannis]

You have nested the spam object under paths. It should be on the same level. You also have a typo in the property itself. It’s blocked_email_domains (singular email), not blocked_emails_domains.

This should work:

    ...,
    "process": "systemd",
    "paths": {
        "contentPath": ...
    },
    "spam": {
        "blocked_email_domains": [
            "txt.att.net"
        ]
    }
}
