not sending email

[gcasali01]

Hi, I have a general smtp relay on port 25 without tls and no authentication , but setting up with notification via email I don't see smtp notification in the logs :
--set email.enabled=true
--set email.failures_only=false
--set email.smtp.host=
--set email.smtp.port=25
--set email.smtp.username=test
--set email.smtp.password=test
--set email.from_address=
--set email.to_address=
logs
I see only INFO logs of backup completed :
