No.. that's separate problem, please forget about "port.." that I asked on my previous message (its solved already).. but I got problem when trying to send email from qmail (192.168.1.9) via sendmail (192.168.1.8).. I got email replied below:

192.168.1.8 does not like recipient.
Remote host said: 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)
Giving up on 192.168.1.8.

I have added the IP address at /etc/mail/access

192.168.1.9 RELAY

and then rebuild the database, by running below command:

makemap hash /etc/mail/access < /etc/mail/access

and /etc/mail/access/access.db created

and also I already reboot the linux box .. but the same problem still occurs ..

please help
