How can I change the email address that sends Domino notifications after runs?
There is a way for the Admin to do this, though it does require a server restart to take effect.
From the Admin page select the Advanced tab and then Central Config. Then edit the 'com.cerebro.domino.email.notificationFromAddress' tab with the email address you'd like to use. Here is the support documentation for more details: https://support.dominodatalab.com/hc/en-us/articles/207459213-Central-configuration
