Well I suppose that if a) no mail gets delivered to them anyhow and b) they don't have a mailbox or queue, they won't get very far.
Beyond that the only methods I (naively?) am aware of are access control ones, based on where they are trying to connect from. What is the concern? If you fear malicious users, then access control is going to be better because by the time they can connect, but would be denied based on not having a proper user name and password, you have arguably opened up your PoP3 server more than you wanted to. (Although potentially "noisy", they can try to bruce force if given access.) Can you arrange for your ftponly users to have a different range of IP numbers than others and then not allow them to connect to the PoP3 server with tcp wrappers and / or firewall ?
