Stalwart mail server

This container bundles stalwart mail server and auto-configures it for you.

Notes

• This is only intended to run on a VPS with static ip-address.
• Check with sudo netstat -tulpn that no other service is using port 25, 143, 465, 587, 993 nor 4190 yet as otherwise the container will fail to start.
• You need to configure a reverse proxy in order to run this container since stalwart needs a dedicated (sub)domain! For that, you might have a look at https://github.com/nextcloud/all-in-one/tree/main/community-containers/caddy.
• Currently, only mail.$NC_DOMAIN is supported as subdomain! So if Nextcloud is using your-domain.com, Stalwart will use mail.your-domain.com.
• The data of Stalwart will be automatically included in AIOs backup solution!
• After adding and starting the container, you need to run sudo docker exec -it nextcloud-aio-stalwart configure.sh and follow https://stalw.art/docs/install/docker/#choose-where-to-store-your-data (1. choose Local disk using Maildir, 2. choose No, create a new directory for me (or select LDAP if you have an LDAP server), 3. type in your $NC_DOMAIN as domain name and mail.$NC_DOMAIN as server hostname. 4. add DKIM, SPF and DMARC as advised to your DNS config, 5. Take note of the administrator credentials, 6. Now the config script should exit and automatically restart the container and enable your config.
• See https://stalw.art/docs/directory/types/memory/ how you can easily create new user accounts. (Alternatively see https://stalw.art/docs/directory/types/ldap if you have an LDAP server). You can edit the config file with sudo docker exec -it nextcloud-aio-stalwart vi /opt/stalwart-mail/etc/config.toml. Also, you might want to enable logging to stdout so that you can see the stalwart logs in your container logs via sudo docker exec -it nextcloud-aio-stalwart vi /opt/stalwart-mail/etc/common/tracing.toml (you need to restart the container afterwards with sudo docker restart nextcloud-aio-stalwart in order to apply the settings).
• Afterwards, you can visit the basic admin settings in https://your-nc-domain.com/settings/admin and add the your mail server for outgoing mails there.
• Additionally, you might want to install and configure snappymail or mail inside Nextcloud in order to use your mail accounts for sending and retrieving mails.
• See https://stalw.art/docs/faq for further faq and docs on the project
• See https://github.com/nextcloud/all-in-one/tree/main/community-containers#community-containers how to add it to the AIO stack
