After installation email is set to "Log file only", so nothing is sent until you enter your mail server.
- Open Admin › Notification settings › Email setup and choose SMTP.
- Enter the host, port, encryption, username and password from your hosting or email provider, and the "from" address.
- Open Test email and send one to yourself.
Every email WAGroups sends (link approved, link rejected, new link waiting, password reset…) is an editable template under Email templates, and the Delivery log shows what was sent.
