These are both Gmail accounts that are forwarding to each other. Does anyone know what happens in this situation?

This black hole would cause a single email to get sent back and forth quite rapidly between the two accounts. I'm guessing this happened so quickly, that Gmail flagged the account as a bulk spamming account and moved the messages into the Spam folder.
