| This mailserver setup follows Workaround's [[https://workaround.org/ispmail-bookworm/|SPmail guide for Debian 12 “Bookworm”]]. Key changes are that instead of installing on Debian 11 virtual machine<sup>1</sup>, with a Maria mysql database<sup>2</sup>, this setup is for installation on latest Alpine linux Docker image with s6-rc init using sqlite database. | This mailserver setup follows Workaround's [[https://workaround.org/ispmail-bookworm/|SPmail guide for Debian 12 “Bookworm”]]. Key changes are that instead of installing on Debian 11 virtual machine<sup>1</sup>, with a Maria mysql database<sup>2</sup>, this setup is for installation on latest Alpine linux Docker image with s6-rc init using maria database. I toyed with sqlite and basically got it functional, however the support apps do not function with sqlite. |

| - The database requirements for a small mailserver with a few dozen domains, with each domain having hundreds of emails and aliases is well within the capacity of the sqlite database. The use of a full multi user server / client relational database is not necessary, particularly for a Docker based server implementation.

| I got the Docker emailer server functional mid 2023. It still needs some more work. Currently I run the mail server 2 containers, I would rather have it all in one container. The email server could also have some more optimisations performed. | <fc #008000>I got the Docker emailer server functional mid 2023. It still needs some more work.
