We do exactly this at FastMail, but we use a different approach.  All
user connections are via an nginx proxy, and the authentication daemon
used by nginx will return an error if the user tries to log in via POP.
It will also send them an email explaining the policy and offering them
an option to upgrade to an account level that does support POP...
