Hello.
It's very unclear to me who is the sender of this mail. It has been
a few weeks or months since some senders are hidden. For those, the
sender's address shown by Thunderbird is "dng@???". This is
the case of this mail, and, BTW, there even is no name at the end.
This mail pretends to be a response to "peter@???".
Normally this should be just true, but I wonder if this isn't the actual
sender's address instead.
Could someone at Devuan explain what has changed and why some
sender's addresses are hidden in this way?
Thanks.
