Restore primary admin account

Hello, by mistake I have deleted my admin user, the one that was created at the beginning of installing MIAB, I already managed to put another user as admin from the CLI to enter the Admin-Panel and create the admin email account again, but it won’t let me, How can I restore it?

Message in admin panel:

“You may not make a user account for that address because it is frequently used for domain control validation. Use an alias instead if necessary.”

Perhaps rerun mailinabox, the install tool?

Thanks, yeah, i already try that but it doesn’t work, what works as a workaround was to edit the file:

management/mailconfig.py

comment line 264 and 268

and restart mailinabox.

And recreate the user via admin panel.

then uncomment again an d restart again mailinabox.
