This configuration is intended to be used with a [Mailu](https://git.autonomic.zone/coop-cloud/mailu) instance which is setup **on the same VPS**. The two configurations for Mailu and Mailman remain separate however. We use shared networks and volumes to share configuration between the two stacks. The hope is that it will be easier to manage them as separate configurations. This is very much an experiment.
- you have overlay networks configured for both your Mailu and Mailman3 stacks (see `SMTP_HOST` and `SMTP_NETWORK` in the [.env.sample](./.env.sample) on the mailman side and `MAILMAN_CORE_NETWORK` [in the mailu config](https://git.autonomic.zone/coop-cloud/mailu/src/branch/main/.env.sample) on the mailu side)
- you have a shared volume between your Mailman3 and Mailu stack which exposes the mailman generated aliases which can be fed into a postfix override on the mailu side (see `MAILMAN_CORE_VOLUME` [in the mailu config](https://git.autonomic.zone/coop-cloud/mailu/src/branch/main/.env.sample) on the mailu side)
