Your MUA has completely mashed this email thread.
Can you make it not do that? Or switch to something better?

You should post the xpra server log output found in the journal.
If the process is running by can't be found with "xpra list" then maybe
its sockets were not created, or not in the right place.
You could always try to bind it to a TCP port and see if you can connect
to it that way.
