+Mailhog can be accessed via ports {{ .Values.service.port.http }} (HTTP) and {{ .Values.service.port.smtp }} (SMTP) on the following DNS name from within your cluster:
+{{ include "mailhog.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
+
+If you'd like to test your instance, forward the ports locally:

+Web UI:
