Thank you for escalating your problem.
You need to configure your Mail Server to get emails working.
If you haven't configured it yet, you can execute below query to configure the same
UPDATE `kaldin`.`email_settings` SET `host` = "SMTP URL", `port` = "SMTP PORT", `mail_from` = "From Email", `user_name` = "SMTP Login ID", `password` = "SMTP Login Password", `auth_flag` = 1, `contype` = "SSL/TLS OR PLAIN";
To reset admin password, use 'Forgot Password?' link on the login page(Administrator Login).
Thanks,
