Hi Nukak,
Thanks for the response. For my understanding, are you saying that is a certificate failure on the client’s mail server? They are using a self-signed cert. Do they need to purchase a valid cert & will that solve the issue?
Edit: Also, I did reach out to hosting (AWS) and they provided the same link to the github article.
