Notification Matcher No Emails

[Kev7274]

I have an email account setup for notifications,but when I run a backup in Proxmox,I'm not getting any emails.

I can run this
"This is a test message sent from postfix on my Proxmox Server" | mail -s "Test Email from Proxmox" myemailaddress@gmail.com
and the email come through fine.
I can also sent an email from another address to the dedicated email address for notifications and I get those emails,so the email address is working that that sense. A test in Notification Targets also works.

Here the backup job settings...


And Notifier settings....
