Comment (by BjornW):

 @ocean90 thanks for cleaning up my description and pointing out the parent
 issue.

 For completeness sake I'd like to add that if the From header is set
 explicitly the problem described in this issue will not arise.

 I've made a small plugin which explicitly sets the admin_email as the From
 address (with the From name WordPress). In my case this solved my problem
 for now.
