Missing From Model

I was able to solve this for the time being making a copy of the Recipient model and renaming everything as From
You can also just use the Recipient model vs creating a whole new model but that kinda defeats the reason to have its own names makes it hard to understand why you would be using a Recipient model for a From function.
Example code of how it has been implemented.

    $rrrr = new Model\From();
    $rrrr->setEmailAddress(array('address' => $from_mailbox));
    $message->setFrom(($rrrr));

This ensures the from address is set correctly and the email will send.

Beginne damit, das bestehende Recipient-Modell mit der im Issue vorgeschlagenen Verwendung von Model\From zu vergleichen, und prüfe anschließend, wie setFrom und setEmailAddress diese Modellobjekte behandeln. Als erledigt gilt die Aufgabe, wenn das From-Modell die Absenderadresse korrekt setzen kann und die E-Mail wie erwartet versendet wird.
