I've been seeing a lot of that lately. Google seem to have tightened their email security practice recently. It appears that 1blu is doing something that GMail doesn't like. They probably have a number of users who have the same problem. I would ask them to check their MTA configuration against the section "Make sure your messages are authenticated" in the referenced page (https://support.google.com/mail/answer/81126#authentication). > ----- Forwarded message from Mail Delivery System > <mailer-dae...@ms-10.1blu.de> ----- > > Date: Thu, 10 Mar 2022 18:48:05 +0100 > From: Mail Delivery System <mailer-dae...@ms-10.1blu.de> > To: g...@unixarea.de > Subject: Mail delivery failed: returning message to sender > > This message was created automatically by mail delivery software. > > A message that you sent could not be delivered to one or more of its > recipients.
