the problem your gmail setting, you should remove the ENV as you put string directly to it (as my understanding this is your local development this will generate an error since you also put config.action_mailer.raise_delivery_errors = true

  config.action_mailer.smtp_settings = {
    :authentication => :plain,
    :address => "smtp.gmail.com",
    :port => 587,
    :domain => "mail.google.com",
    :user_name => "******@gmail.com",
    :password => "******",
    :enable_starttls_auto => true
  }
