Dear Maintainer,

I find it currently annoying that I can't send E-Mails to Debian bugs from
a specific computer, b/c this is the one I work mostly with. The phenomenon
started about 3 weeks ago. The mails are simply not received, neither they
are visible in the BTS web interface nor do I get the confirmation that the
mail was received.
The computer is running Windows 10, mail client is Betterbird. Another computer
in the same network running Debian stable and Thunderbird can send mails, same
for the third (Debian stable and mail client mutt). All mail client use the same
mail relay so I guess the relevant mail configuration should be equal.

Many thanks,
  Hilmar

To enable us to investigate errors or problems you should provide us
with the following information (or as much of it as possible):

 * the IP,
 * the Time (including timezone),
 * the Message-Id,
 * the Addresses you sent from and to,
 * anything else that you think would help

We maintain a system which receives and sends more than 1,000,000
mails a day. Without the information above we have little chance of
finding out what went wrong.

Hello Don,

Many thanks for the answer.
I sent another E-Mail, I put me in Cc, so I have the mail header,
which is attached. I contains 3 headers "Autocrypt",
"UI-OutboundReport" & "UI-InboundReport", which i mainly snipped, b/c
I don't know which information they really contain.
