Hi Dale,
Thank you for your reply.
In the manage Backup screen there are the cron backups only.
So, why I got this king of notification ?
I have checked my emails and I never had these messages before the 27/06/05.
It can't coming from a "clone site" because :
1- I have no clone
2 - the email address is not public and created/used only to get specific messages
I have read the journal of the last backup (a cron job) and saw these lines :
DEBUG |170608 06:02:10|-- Fetching mailer object
DEBUG |170608 06:02:10|-- Joomla!'s mailer is using mail mail method.
DEBUG |170608 06:02:10|-- Creating email message
DEBUG |170608 06:02:10|-- Sending message
DEBUG |170608 06:02:10|-- Email sent
The email has been received at the same time and I had received another with the resume process of the cron
Maybe important : the notification is only for 3 domains, each one hosted by different servers... but there are other domains with the same configuration of akeeba on these servers
