Camram is an anti-spam system that for the first time makes practical the holy grail of sender-pays email. It forces spammers to expend unsupportable levels of effort while imposing negligible burdens on everyday users. Its "hybrid sender-pays" design provides anti-spam benefits to the first user that adopts it, while supporting graceful scalability to massive numbers of users.
