these settings are required in elib.yml:
---

email_password: <email provider password>
email_host: <email provider host>
email_port: <email provider port ("25")>
email_from: <email from user (e.g. "[email protected]")>
email_organisation: <(e.g. "Online Vibes")>
email_recipient: <where to send contact form emails - can be different than email_from>
