Got a solution at least for https://schwefel-bor.de !

My WordPress version is 4.8, I haven’t changed this.
I’ve installed plugin WP Rollback and rolled back to
Contact Form 7 version 4.7.

It’s hard to believe, but now everything is working fine again.
Hope, it’s working for you.

I get rid of Contact Form 7 plugin as soon as possible.
