I would like to set a regex that will whitelist an allowed domain for all email notifications.
The reason i would like to do this is so that i dont have to worry about email reports being sent out of the organization and hopefully avoid further questions from any future audit of the implementation of Splunk.
If this was something that could be set in the email settings manager that would be perfect or if there is a way to add that validation/whitelist in a conf file for now that would be great as well.
normally i would tackle this with the MTA but i dont own the OS on the servers (managed by another group) and have limited access to change OS base settings.
Any ideas where I could try this whitelist idea to prevent possible data leaks via emailed reports?
