email_settings["HAVE_BLACKLIST_USERNAMES"] missing?

[huglester]

Hello

Looking at this:

Version 1.60.0 | Directadmin Docs

DirectAdmin Knowledge Base

docs.directadmin.com

CMD_ADMIN_SETTINGS?json=yes

should return in json some data about blocking email OUT.

But JSON output does not contain this information:
email_settings["HAVE_BLACKLIST_USERNAMES"] == "yes"


Any idea how to "enable" it?

Thanks.
