+# Sending e-mails
+To be able to use the `mail()` function in PHP you need to install a MTA (Mail Transfer Agent) in the container.
+
+The most simple approach is to install `ssmtp`.
+
+The `ssmtp.conf` file needs to be created based on the [documentation online](https://wiki.archlinux.org/title/SSMTP).
+
+```Dockerfile
+FROM trafex/php-nginx:latest
+
+# Install ssmtp
+RUN apk add --no-cache ssmtp
+
+# Add configuration
+COPY ssmtp.conf /etc/ssmtp/ssmtp.conf
+```
