I think the question is more along the lines of: "In case some customer changes the MX records away from me, how can I automatically stop accepting mail for that domain?" About the best you can do is probably a cron job that checks on MX records for domains you supposedly host, that can lead to automatically disabling domains that suddenly point somewhere other than your mail system. -kgd
