# Mailhog

[MailHog is an email testing tool for developers](https://github.com/mailhog/MailHog).

## In cluster SMTP service

Ypu can send ESMTP emails in the cluster to `mailhog.mailhog.svc.cluster.local`, standard port `1025`, as defined in the service manifest:

```yaml
apiVersion: v1
kind: Service
metadata:
  name: mailhog
spec:
  ports:
    - name: smtp
      port: 1025
```

## Ingress

Mailhog offers both WebUi and API at `https://{{{ .Env.DOMAIN }}}/mailhog`.

The ingress definition is in `stacks/core/ingress-apps/mailhog.yaml` (BTW, why isn't this ingress file here in this folder ??) routing to the mailhog' service

```yaml
spec:
  rules:
  - host: {{{ .Env.DOMAIN }}}
    http:
      paths:
      - backend:
        ...
        path: /mailhog
```

## API

For usage of the API see https://github.com/mailhog/MailHog/blob/master/docs/APIv2.md
