Hopefully this exampels will help people get up to speed and deploy the solution faster. They show how the image can be used in different scenarios, e.g.: - as a MTA for Dovecot with `docker-compose` - as an outgoing queue towards AWS SES or Google Mail through `helm` - as an outgoing queue towards Sendgrid through `helm`
