We are a free and open source software project. We set-up a Google Group for build results from services like Travis, AppVeyor, CodeFresh and Coverity. The list does not allow Public to post since we want to avoid all the viagra, penis enlargement, religious and other useless posts that flood a list.
We are trying to configure a whitelist for the group because sender email addresses, like
email@example.com, are not monitored. There's no one to interact with an invitation or a challenge system.
I found the Manage link, but I cannot figure out how to add the desired email addresses so the services can post to the list. Searching is not turning up much information, either. I'm guessing I have not used the correct keywords.
How do we whitelist the addresses so the build services can post to the group?
