exim-relay

Base from work of https://github.com/selim13/docker-exim-relay

This is a base Exim docker image configured to act as a relay with some basic main, acl and retry defaults.

No routers, transports or authenticators are configured, so by default it will fail delivering all mail.

You can use it as a base for your docker images. Put your configuration either to /etc/exim/exim.conf or to the following included files:

• /etc/exim/conf.d/main.conf
• /etc/exim/conf.d/acl.conf
• /etc/exim/conf.d/routers.conf
• /etc/exim/conf.d/transports.conf
• /etc/exim/conf.d/retry.conf
• /etc/exim/conf.d/rewrite.conf
• /etc/exim/conf.d/authenticators.conf
• /etc/exim/conf.d/local_scan.conf

Environment variables
