I stumbled across a Gmail Group guide from a couple of years ago. Basically I followed its steps and created a group with the name@googlegroups.com format. I logged into my original address and went to `Settings > Forward and POP/IMAP, added the Google Group address and it says it sends a confirmation message. The thing is, where does this message go to? It doesn't show up on the original address inbox nor does it show up in the group itself.
