Setup SMTP

In order to send emails from your Hudu, you will need to provide a SMTP server. If you are looking for a free (for the number of emails Hudu has to send out), easy one to setup, we recommend SMTP2GO. You can test the SMTP connection by going to the Hudu Admin > Self-Hosting Center > SMTP Test, when logged in to your instance.

Example credentials for different providers.

Gmail.

Be aware that Gmail has strict sending limits. For growing organizations, please look into using a transactional email service like Amazon SES or Mailgun.
    SMTP_DOMAIN=smtp.gmail.com
    SMTP_ADDRESS=smtp.gmail.com
    SMTP_PORT=587
    SMTP_STARTTLS_AUTO=true
    SMTP_USERNAME=username@gmail.com
    SMTP_PASSWORD=password
    SMTP_AUTHENTICATION=login
    SMTP_OPENSSL_VERIFY_MODE=none
    SMTP_FROM_ADDRESS=username@gmail.com
  
With Gmail, try turning on 2-step validation and using an application password. Alternatively, enable less secure apps to access the account.
