      - /etc/pki/tls/private/webmail.somedomain.uk.key.pem:/etc/nginx/ssl/key.pem:ro
      - /opt/docker/snappymail/ssl/dhparam.pem:/etc/nginx/ssl/dhparam.pem:ro

⁠SSL

The container has SSL enabled by default and expects the certificate chain and key to be available at the following locations inside the container:

• /etc/nginx/ssl/cert.pem
• /etc/nginx/ssl/key.pem

For added security I have added a dhparam parameter in the nginx configuration so it expects a dhparam.pem file at the following location:

• /etc/nginx/ssl/dhparam.pem

⁠Changes

I have introduced a "stable" tag instead of the "latest". The "latest" tag will be the git "master" branch while the "stable" tag will be the latest git tag.

For changes in the different versions see my github⁠ repo's commit messages.
