Well, that only proves the sender, Juergen Gross, intended to send it to me.
So far, I have not found any evidence the message was delivered to my
Inbox. The evidence I have obtained so far in my filesystem and from my
e-mail provider and the messages I have received through my e-mail provider
is that the message was never delivered to my Inbox, and based on that
evidence, my current theory is that my e-mail service provider silently
dropped the message because it was signed. I will report the full findings
of my investigation here when my investigation is complete.

The only way I was able to respond to the message was by downloading
the mbox file from lore.kernel.org and importing it into my e-mail client.
So it is a fact that it was more difficult for me to respond and defend myself
against the attack that Juergen made against me because I had to go to the
trouble of finding the message on lore.kernel.org and import it into my
e-mail client instead of just using the ordinary procedure of replying to
a message I received in my Inbox.

Best regards,

Chuck
