Fixes: 26f289b7 ("Capitalize the first letter of all task names")

ansible-lint 6.5.0 complains about:

  name: All names should start with an
        uppercase letter. (name[casing])

These are used to signal the start of the document in a stream of many
documents. As Ansible only supports one YAML document per file this is
unnecessary. About a third of our YAML documents already lacked these.

No one uses it and less to worry about.

Fix #205

The homedir is now /home/vmail/%d/%n instead of /home/$USER.

Preparation for switching to a virtual user setup and removing all the
staff users from mail.a.o.

yaml: truthy value should be one of [false, true] (truthy)
yaml: wrong indentation: expected 4 but found 2 (indentation)
yaml: too few spaces before comment (comments)
yaml: missing starting space in comment (comments)
yaml: too many blank lines (1 > 0) (empty-lines)
yaml: too many spaces after colon (colons)
yaml: comment not indented like content (comments-indentation)
yaml: no new line character at the end of file (new-line-at-end-of-file)
load-failure: Failed to load or parse file
parser-error: couldn't resolve module/action 'hosts'. This often indicates a misspelling, missing collection, or incorrect module path.

This sets the dovecot ports for imap and pop3 to 0 which disables those
services. For SMTPS we add the the SMTPS service on 465 first before
deprecating support for submission on 587.

While mbox and maildir files get deleted by dovecot right away, that's
not the case for mdbox files. Since they contain multiple mails at once
in a proprietary format rewriting is expensive. That's why this step
is done in a separate step outside the dovecot process.

Switching to Rspamd has some advantages:
* It is probably faster than SA[1] (C + Lua vs Perl)
* We can reduce the number of moving parts. Rspamd has built-in DKIM
  signing, greylisting, DMARC checking to name a few
* It doesn't just mark the mail as spam/not-spam, it gives every mail a
  score and depending on the score it does either: nothing, greylist it,
  mark it as spam or reject it[2] (more actions is available and it can
  be tweaked)
* Replies whitelisting[3]
* It supports ARC signing, which can be useful
* A cool looking WebUi :)
* ... and more[4]...

This enables lastlog so that we also see which accounts are used for
email only even if they are not used for SSH.

The discovery script now uses a regex and no longer cares where exactly
accounting is enabled. Follow systemd upstream by enabling it by
default.

Disable firewall because python2 module is not avaible and the tasks
fail which makes the playbooks fail and leads to handlers not being run.
