u can use relay-ctrl. what it does is "smtp only after pop3".
a local user retrieves mail via pop3. relay-ctrl saves his IP for 15minutes.
during those 15minutes, he can use peculiar for smtp. After thosee 15mins,
relay-ctrl deletes the IP.
this way, your box will never be an open relay. U just have to instruct your
users that they can only send after retrieving.
i use this, and works great.
check qmail's page for where to find the program.
