Best Way to Control Relaying?

[Muhammad Nauman]

I Have No Ip In the Access file - and i am Using SMTP Auth - with SASL.

It is that - When i do check the box in my e-mail setting to ask for 
Authentication - its works fine.

But when i uncheck the box, it still do'nt block sending - which it should 
!!!

Is there any other way - Sendmail - auto matically starts building the 
whitelist ???

Thanks and Regards,
