Forth, this may violate US EPCA user expectation legal provisions.  Not
sure if it matters to you.

Neither living in nor caring about the USA: not at all. German and EU

Yes, it was accepted and subsequently put into the junk bin. Recipient's
decision, not some entity during transport.

It would nice  to know what headers it added or will behave like Hotmail
and the SendMail accept and junk too?  Is this system supporting PRA?
