With upcoming changes to the dovecot home and maildirectories we need to introduce a way to nudge users to inform themselves about manual migration steps they might need to carry out. The idea here is to allow us to safely make breaking changes and notify the user of required migration steps at eval time, so they can make the necessary changes in time.

==========
|
|
|
|
With mail server configuration best practices changing over time we might need
|
|
to make changes that require you to complete manual migration steps before you
|
|
can deploy a new version of NixOS mailserver.
|
|
|
|
The initial `mailserver.stateVersion` value should be copied from the setup
|
|
guide that you used to initially set up your mail server. If in doubt you can
|
|
always initialize it at `1` and walk through all assertions, that might apply
|
|
to your setup.
|
|
|
|
NixOS 25.11
|
|
-----------
|
|
|
|
This option was introduced in the NixOS 25.11 release cycle, in which case you
|
|
can safely initialize its value at `1`.
|
|
|
|
:: code-block: nix
|
|
|
|
mailserver.stateVersion = 1;
