I don’t have possibility to change the smtp serverMail could not be sent to the admin user. Please check the admin emailid/Server settings”

I have tried many settings, and it is not working, and it looks in the database it never changes.

So what I have done is go to database and change vtiger_systems directly by change the values into

id: 1
server: localhost
server_port: 0
server_username: “CRM_USERNAME”
server_password: “CRM_USERPASSWORD”
server_type: email
smtp_auth: false
