We are using contact form 7 on a managed WP 1&1 IONOS instance (WP 5.1.1).
In the response e-mail that we get, all the form variables (tags) are not replaced. Instead of the values, we see the field names like:
[firstname] [lastname]
The email is well received, but without the actual data

After some serious digging around, we found that this behaviour/bug was triggered by a filter called wpcf7_posted_data.
Furthermore, we found that a plug-in in the wordpress mu-plugin folder was causing the problem. The plugin is enforced by 1&1 IONOS, and is called "cozy-address-book".
Since we cannot disable this particular plug-in, we rename the whole mu-plugins folder.
After that, contact-form7 worked totally fine and the data is submitted.
We will reach out to 1&1 and will ask for a permanent solution.
