Hi Everyone,

When setting up a group there is this option:

 ![32%20PM](https://global.discourse-cdn.com/meta/original/3X/9/0/90996badab8c9703161e915b7972c4fea2c1aea6.png)

I would like the inverse of this behavior, to add anyone who **does not** come from my clients email domain (e.g. `*foo.com`) to be added to this group.

Is it possible to do this?

This is not possible to my knowledge.
