Oh sorry, didn't see the last part of your comment! It's called Lightermail because once you start using it your inbox and email flow get a whole lot lighter :)
Lightermail allows you control when and from whom you receive email (from the global level to individual TLDs to specific senders). The who and when are highly configurable. You can also combine your unimportant email into summaries to reduce the actual quantity of email that lands in your inbox.
