Mail is not sent, collected info doesn't show up

[SteffiKn]

eZPlatform Version 2.4

I followed the documentation, the form is displayed and I can send it. Seemingly successful, at least I get the success message.
I use a seperate template for email:
email: templates: default: "email/form_collect_data.html.twig"

which only contains the email block and a sample text:
{% block email %} New mail received through example.de website! {% endblock %}

In the app/config/ezplatform.yml file I configured to execute both 'email' and 'database' as default actions.
The default_variables all contain valid values of course.

Maybe some configurations are missing? Unfortunately I couldn't find any further configs for sending mails or saving the collected data of the form fields.

I expected that in the admin panel a new tab is showing up as soon as there is data collected the first time.

Any Ideas on what is wrong or missing?

@SteffiKn can you see collected information in admin? Do you see the email in Symfony Profiler toolbar?

[SteffiKn]

@MarioBlazek
No, there is nowhere collected information in the admin gui visible. Where should it be?
The email is not sent, but I found the database entries for the form values in the table 'ezinfocollection_attribute'.

@SteffiKn which version of InformationCollectionBundle do you use?
