Mail function working properly on localhost but on godaddy server sending email on junk

I am have having Go daddy shared hosting, in which we are running laravel php system.
Now when we are sending email using Mail::send it is ending up in junk.

here is my ENV file details

MAIL_DRIVER=sendmail
MAIL_HOST=smtp.rediffmailpro.com  
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=password
[email protected]
MAIL_FROM_NAME="[email protected]"
MAIL_ENCRYPTION=tls
MAIL_FROM_NAME="Test Name"

Are we using proper setting, or Godaddy should use different setting
