Yes right, this solution works. Make sure that the email in EMAIL settings, Server Support Contact and admin ID is the same. Also Check the option emailonlyfromnoreplyaddress in the email settings.
Make sure that sendmail() functions works and so is the service on the server.
Thank you to you all
This works with the checkbook on the noreply
