Yes, i've tried, it start with a new full backup.
Now backup works regurarly as before the update.
But i have a problem with mail notification: no mail is received !
Our new mailserver is on microsoft office 365 server. In the spam nothing is received.
Our "nethserver" server hasn't a public domain. It's part of the internal network.
I've tried also with gmail and aruba mail address with the same result, no mail are received.
I suspect that the mail are rejected by the mail server because it doesn't contain all data like dkim, spf.. data that cannot be inserted by a server that hasn't a public domain.
How to control that the mail has been sent ?
Can the mail been sent using an external service to be sure that the mail contain all data and sign to be marked as regular mail ?
