Relaying denied by Postfix

[Sunil Punnachalil]

Hi,

I don't know this is the right forum to post this
question, if not I applogize for this.


I am running a SuSE 8.1 on a PowerEdgege 1600SC with
Postfix and Cuyrus configured with SASL. When ever I
try to send mail to local users (user at mydomain.com) I
get relaying denied message in mail log and none of
the local users can receive mails. But I can send
messages by user at localhost and user can receive mails.
I am also able to send mails out side the net work.

I greatly appreciate if some one can help me on this.

fillowing is my postconf -n
