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).
