Only two methods I have implemented.

2) "SMTP AFTER POP" - The client need to check his mail first and for a set 
amount of time he can send mail through that same server.
3) The best solution though would be "SMTP AFTER AUTH". Setup a seperate 
smtp server which allows any user to relay mail after authenticating 
himself. I have done this using POSTFIX+SASL+MYSQL. Quite robust can handle 
tons of mails.
