One website is sending emails by php. DKIM is enabled. But the test is failing.
Head of email:
Sender host: two.stauss-alpha.de (62.116.188.252)
Sender (Return-Path) address: katjahar1@two.stauss-alpha.de
This is subdomain of server not of website.
The DKIM fails, because there is no record on two.stauss-alpha.de only on website domain.
Why here is not domain and email of website submitted?
