553 Relaying dissallowed

Hello, I have this problem trying to send email through a Laravel app, I have checked the MX records and they seem fine, I can send and receive emails through the web interface, but setting the SMTP configuration in the PHP environment, I get the error: 

Expected response code 250 but got code "553", with message "553 Relaying disallowed as Example < hello@example.com>

I checked the "Send email as" and the email address is set there.

I tried TLS and SSL config:

  1. MAIL_DRIVER=smtp
  2. MAIL_HOST=smtp.zoho.com
  3. MAIL_PORT=587
  4. MAIL_USERNAME=ventas@arcosyflechasecuador.com
  5. MAIL_PASSWORD=zoho-email-password
  6. MAIL_ENCRYPTION=tls
