You can deploy a fake smtp server which captures all send mails and displays them in a web interface. The sample configuration is assuming such a dummy server in the SMTP_HOST configuration and points to a cluster-internal SMTP server.

To deploy the SMTP server just uncomment the relevant code in the ingress server configuration and run the following:

# in folder deployment/ocelot-social
$ kubectl apply -f mailserver/

You might need to refresh the TLS secret to enable HTTPS on the publicly available web interface.
