Initial support for DKIM and testing This commit brings two important features: - DKIM support It's now possible to configure this postfix image to sign messages using DKIM by simply generating the keys and providing them in the approprate folder. This should bring us one step closer to directly sending out emails without relying on a 3rd-party proxy. - test support A nice and handy script, conviniently called `test.sh` has been provided, builds the image, spins it up and tries to send out an email. You'll need `docker-compose` to run it, though. 2019-02-19 17:49:55 +08:00			`#!/bin/sh`
Fix for #30 - Use sleep inifinity instead of sleep <number> Apparently using sleep with very large numbers is not a good idea when your image can be compiled down to 32-bit platforms. This fix uses `sleep infinity` and -- failing that -- tries to sleep for about 68 years (which is exactly 2^15 seconds). 2020-08-16 04:45:49 +08:00

OpenDKIM keys have been moved to the `keys` folder This is to make it easier to integrate with Kubernetes to be able to bind a `ConfigMap` to the said folder. 2019-02-19 18:42:16 +08:00			`elif [ -z "$(find /etc/opendkim/keys -type f ! -name .)" ]; then`
