no more mail message after backup completion latest version

[tradexsrl]

Hi , is about a few days i'm not receiveing anymore the mail message after the backup completion
backup run because i saw in the nfs mnt the backup file and also in the local /backup directory
i open the backup.env and i have found the main method to send message is relay and then fall back to pfm , the from message is your domain
maybe there is a problem in your server or the script do not fall back to pfm anymore
