Problem in creating the Tickets in Request Tracker through Email


I am running RT 2.0.15 on Red Hat 9. Request Tracker is not able to
generate the ticket when I am sending the mail to the RT. I have tried
generating tickets through web interface and which is working fine.
Below mentioned is the log of maillog for your reference. If somebody
knows the answer for this problem, please help me.

Extract from the maillog:
