Email after backup job

[cr_eis]

Hello,
From the proxmox hypervisor I have set up the VM backups. After the backup I have to receive a report by email.I set up postfix using authentication. I receive the test email by typing this command.

echo "Test mail from postfix" | mail -s "Test Postfix" destinataire@mail.com

However, I don't receive the email of the backup report even though the postfix logs indicate that it is gone. I don't find it in my spam either.

Does anyone have an idea about my problem ?

The relay smtp.orange.fr accepted it, so it is either there or on your downstream mail server that it gets dropped.

the problem was with the smtp server. The test mails were well sent not those coming from the vzdump backup. I used another smtp server to make it work.
Thanks
