Hello,
We have same problem
For several days, we have encountered a blocking phenomenon on several of our customers despite a perfect configuration of our mail servers.
We use the Google business solution on all of our domains.
Example of a domain name with this message:
dkgroup.fr
bati-avenir.com
b2mconstruction.be
dkdigital.fr
dkprinting.fr
As well as all of our other domains, the most used being dkgroup.fr
Thanks for your help.
