Getting alert Emails from root and not from name i configured.

I have managed to resolve this issue by removing the comment from the following line in the /etc/ssmtp/ssmtp.conf file:

FromLineOverride=YES

It takes effect immediately but my concern is that "this is an auto-generated file - do not edit" and that it therefore may not survive a system restart.

Is there a "proper" way to configure this property?
