+# Sending and capturing email
+
+Sending/capturing email support can be added via [MailHog](https://github.com/mailhog/MailHog).   
+
+    Out-of-the box only capturing will be working.
+    For email delivery you will have to point MailHog to a working mail server/service.
+
+## Setup
+
+1. Add the `mail` service in `docker-compose.yml`
+
+    Replace `<project_name>` with your project name.
+
+    ```
+    mail:
+      hostname: mail
+      image: mailhog/mailhog
+      expose:
+        - "80"
+      environment:
+        - MH_API_BIND_ADDR=0.0.0.0:80
+        - MH_UI_BIND_ADDR=0.0.0.0:80
+        - DOMAIN_NAME=mail.<project_name>.docker
+        - VIRTUAL_HOST=webmail.<project_name>.drude
+    ```
+
+2. Apply new configuration
+
+    ```
+    dsh up
+    ```
+
+3. Install sSMPT in cli
+
+    ```
+    dsh exec "sudo apt-get update && sudo apt-get install ssmtp -y"
+    ```
+
+4. Configure sSMPT in cli
+
+    Replace `<project_name>` with your project name.
+    
+    ```
+    dsh exec "sudo sed -i -e '/mailhub=/c mailhub=mail.<project_name>.docker:1025' -e '/#FromLineOverride=/c FromLineOverride=YES' /etc/ssmtp/ssmtp.conf"
+    ```
+
+MailHog web UI will be available at `http://webmail.<project_name>.drude`
+
+    These instructions are temporary. Tread them as a POC for using MailHog with Drude.
+    Steps 3 and 4 have to be performed any time the cli container gets reconfigured/updated.
