TYPO3 Core

I have a few questions about this:

- Where did you add these options? My guess is public function get(array $mailSettings) at the type "smtp"?
- Do you have an overview of all StreamOptions?

So that we can implement it in a meaningful way. I imagine an array in the AdditionalConfiguration, which is not editable by the Install Tool. Comparable to the HTTP options ([HTTP][proxy]). Here we have no UI on the part of the InstallTool.

I add a first approach. Maybe you can check this patch and add some feedback?

I added the patch to my Typo3 10.4.21 setup and mail worked again after adding the new transport_smtp_stream_options to LocalConfiguration MAIL:

'MAIL' => [
    'transport'                     => 'smtp',
    'transport_sendmail_command'    => '/usr/sbin/sendmail -t -i ',
    'transport_smtp_encrypt'        => false,
    'transport_smtp_password'       => '',
    'transport_smtp_server'         => 'localhost:25',
    'transport_smtp_username'       => '',
    'transport_smtp_stream_options' => [
        'ssl' => [
            'verify_peer'      => false,
            'verify_peer_name' => false
        ]
    ]
]

However, the 'Configure Installation-Wide Options' in the install tool fails with the patch as "type: mixed" cannot handle the array above:

PHP Warning: mb_strlen() expects parameter 1 to be string, array given in typo3_src/typo3_src-10.4.21/typo3/sysext/frontend/Classes/ContentObject/ContentObjectRenderer.php line 3300

Also, some indentation spaces for the new options are missing in DefaultConfigurationDescription.yaml as well

P.S. yaml is the worst
