qmail 25 port problem

[kapil sharma]

Hi,
I have a strange problem. I am using qmail on redhat linux 6.0. I am running
tcpserver.  My /etc/hosts.allow and /etc/allow.deny files are empty. I am not
using any firewall.
I have following lines in my /etc/tcprules.d/qmail-smtp file and then i made a
cdb files from  it

127.0.0.1:allow,RELAYCLIENT=""
:allow

I have also check with tcprulescheck whether my IP address is allowed to connect
to this smtp port? Now my problem is I am unable to connect to qmail server 25
port from any remote server. I am able to connect from the same server to 25
port.

Please help
