Howdy,
I see a little bit of discussion about docker - and I'm keen to use a docker implementation of EFA.
I'd be happy to help (I'd need help with the building, since I've really only use EFA from a deployed appliance).
I would think that converting to use docker images would enable a couple of benefits:
* Each component (postfix, spamassasin, mailscanner, etc) can be updated independently
* Each component could be scaled independently too
* Folks can deploy it on any linux host, without worrying about installing pre-built perl modules or building the modules (since the docker container images would have all the dependancies as part of the image build). CI/CD could automatically build them too...
* The appliance install image is trimmed down to basically a docker install, a docker composer file and then configuration...
Anyway, some ideas - I want to move my EFA implementation to an existing cloud host which is running docker containers and being able to move the EFA components would be useful. If nobody has done it, then I'll have a go anyway...
