Is it possible to configure SMTP relay on SSRS 2012 RTM?


I am trying to configure SSRS 2012 RTM to work with user and password to a remote SMTP server. In 2016 its working just fine but for some reason on 2012 it doesn’t- when i add the SMTP configuration below and then i try to create an SSRS subscription it will not allow sending subscriptions that are not file share subscriptions. IS this feature supported in 2012? (SMTPAuthenticate= 1)

configuration file SMTP setup: enter image description here

I also checked the error logs and could not find an error. Thanks In advance
