+# Inbucket chart
+
+[*Inbucket*](https://www.inbucket.org/) is a fake SMTP server that provides all
+captured eMails via a webapp and a REST API. At *Wire* it is used in testing
+environments to not have to deal with concrete SMTP server configurations.
+Especially, it saves us to care about topics like *SPAM filters* and *server
+grey & black listing*.
+
+This chart exists to adjust the [`inbucket/inbucket`
+chart](https://artifacthub.io/packages/helm/inbucket/inbucket) to our needs.
