updating postfix configuration reliably

winksmith · Jun 24th 2023

Is there any way to update postfix configuration reliably? Does it use a prototyping system and can I update the base file to my liking. I want the default to be use TLS, but updates seem to overwrite it. My last instance of OMV didn't have the characteristic of overwriting my configuration. Is there a way to make OMV6 keep my desired configuration? Thanks.

OMV is enabling TLS depending on what you've entered in the UI.

Nevertheless, OMV provides environment variables that allows users to tweak several settings under the hood.

Run omv-env get | grep postfix to get an overview.

Finally you can use Salt states to apply custom configs.

After reading up a bit, it seemed like like the best thing to do would be to create a docker instance for Postfix. I've gotten a lot of that worked out already, but I haven't sorted out the issues with conflicting resource usages for the Postfix already running on OMV6.

Is it possible (or advisable) to run a docker Postfix and the local OMV6 Postfix simultaneously, or will my docker take over that function completely.
