instead of explicit TLS (STARTTLS).
We disabled STARTTLS for IMAP by default in 54f37811dd
and we will likely do the same for (client) SMTP in the future.
As of recently, Nix 2.6 from Ubuntu 22.04 became too old to evaluate
nixpkgs. A new-enough version of Nix is available as part of Ubuntu
24.04, but those newer versions of Nix aren't happy with our rather
primitive proot workaround anymore.
Thankfully, someone already made a version of Nix that does all the
heavy lifting for running in unprivileged environments like the one
Read the Docs provides. So we used that instead.
instead of just smtp:// with STARTTLS.
Opted to call the flag --ssl and not --tls to keep it consistent with
the module option (mailserver.enableSubmissionSsl), dovecot internals
and smtplib in mail-check.py.
Eval does not stop on the first assertion failure it encouters.
Instead, it tries to evaluate all assertions and returns with a list of
those that failed.
This means our very top `config.mailserver.stateVersion != null`
assertion does not gate against any other assertions trying to compare
null against an integer.
The error prior to this commit can be reproduced by removing
`mailserver.stateVersion = 999;` in tests/lib/config.nix and then trying
to evaluate any of the tests:
~~~bash
# nix eval --raw .#checks.x86_64-linux.internal-unstable
