    passwd kush
    

    Add user kush

20. Now let’s test if everything is working

21. Go to https://smtpserver.com/smtptest

22. Add SMTP hostname as mail.yourdomain.com - username - kush, pass - kush, Port 465

23. Mail from kush@mail.yourdomain.com

24. Mail to whateveryouwant-whatever.com

25. 

    If you are not getting mail, check error log using journalctl -xe
