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.

FROM trafex/php-nginx:latest

# Install ssmtp
RUN apk add --no-cache ssmtp

# Add configuration
COPY ssmtp.conf /etc/ssmtp/ssmtp.conf
