Customize From Address in notification email

In the admin area at Email server I filled the input From Address so the email notifications "to be sent" from I used the smtp at Send mode and I filled all the inputs with my google account but at the end the email appears to be sent from my gmail and not from the address

I tried also the php at Send mode but again I didn't received the email from the custom address.

I use the version:
ownCloud 9.1.5 (stable)
