Apache Error after installation of RT3.6

Hi All

I have installed request-tracker3.6 from ubuntu repository and not able
to create ticket through mail. And getting this error in apache:

[Sun Sep 13 11:57:15 2009] [error] [client 127.0.1.1] client denied by
server configuration:
/usr/share/request-tracker3.6/html/REST/1.0/NoAuth/mail-gateway

My /etc/postfix/aliases configuration is as follows

finance-query: “|/usr/bin/rt-mailgate-3.6 --queue ‘finance-query’
–action correspond --url http://finance-rt.india.tejasnetworks.com/rt/
finance-query-comment: “|/usr/bin/rt-mailgate-3.6 --queue
‘finance-query’ --action comment --url
http://finance-rt.india.tejasnetworks.com/rt/

and checked Permission of
/usr/share/request-tracker3.6/html/REST/1.0/NoAuth/mail-gateway is
www-data:www-data and apache configuration is as below:

<Location /rt/REST/1.0/NoAuth>
RewriteEngine On
RedirectMatch permanent (.*)/$ $1/index.html
AddDefaultCharset UTF-8
SetHandler perl-script
PerlHandler RT::Mason
Order Allow,Deny
Allow from 127.0.0.0/255.0.0.0

Include “/etc/request-tracker3.6/apache2-modperl2.conf”
RedirectMatch ^/$ /rt/

Does anyone have any idea what is wrong ?

Thanks in advance
