This seems to be a recurring a recurring problem. Mine has a bit of a twist:
I have 2 forms active
My test mails all arrive. To what ever email address I send it.
One form (#1) works without any problems
Form #2 does not work.
Test emails do arrive, but the form doesn't do anything.
The email account is not blacklisted. I can send emails to it and send emails from it.
So the only thing that does not work is the 2nd form. All the rest seems to work.
I've gone through all setting options. Really ALL.
What am I missing here?
