Hi,
I'm getting an error while configuring the outgoing email settings

Error: "An error occurred while sending mail (end of file reached)"
My settings are:

  email_delivery:
    delivery_method: :smtp
    smtp_settings:
      address: "smtp-mail.outlook.com" 
      port: 587
      domain: "outlook.com" 
      authentication: :login
      user_name: "abcd@hotmail.com" 
      password: "pwd"
