Pls be aware that the png used is not my property nor GPL / GNU and needs to be replaced !

Thanks for Your solution and sorry for that late reply.
I tested it, it worked. But {{ fields.hostname }} does not get populated ( as also in Your images ).

Update:
Never mind. {{ fields.hostname }} only works for "real" messages.
In Testmessages this field is left blank.
