From Add all users to a group - G Suite Administrator Help
You can't edit the members within the All users within your-domain member. But just like any other group, you can edit the groups access settings or delete it.
Note: On 2018-07-17 the above quote continue being valid.
Instead, create a group to which you add the desired members by other means. There are several options for that.
Another note: Suspended users will not receive emails sent to a "everyone" list.
It should be possible to do this now, using Content Compliance. See this answer: https://webapps.stackexchange.com/a/122559
