[Q] How to Configure Qmail to be a Selective NON-Relay

[배성식]

Hi~

I use qmail-1.03 + mysql at RedHat 6.0 for free mail service.

I set control/rcpthosts as empty so my mailserver is open relay.


I want selectively not relay for special sender domain to prevent spam mail.

How can I configure qmail to be a selective non-relay?

I already set control/badmailfrom as following :

    @sbsmail.co.kr

but It seems not work.

thank you.
