This might be what you’re looking for:
It runs through PHP’s mail() function, so also make sure you compiled PHP with that.
Thanks for the tip… but that doesn’t really help… it just shows that there are a lot of problems here that have existed for many years and have never been solved.
I now have an error log showing that the “From” address is missing.

There is a comment on this that is 7 years old and describes that the sender address has to be predefined as a variable since WP version 4.6… but obviously it isn’t.
For testing I use the “WP Test Mail” plugin… this does not transfer a From address in the header and therefore probably doesn’t work.
Contact Form 7 passes the wp_mail function a correctly filled headers array, which also contains “From: “. Still the same error flies… The from is either removed or doesn’t arrive.
And BTW How I wrote, PHPs mail works fine directly called from any script 🙂

I found the Problem 🙂 There was a filter ‘wp_mail_from’ set by an installed plugin. This removed the default sender address 🙂
The decisive factor was the error log without which a problem cannot really be solved 🙂
