Dear All

I have configure DNS and Sendmail on my internal linux behind of Linux Router. (for internal organization mailing itself).
I can send and received mail within internal network but not able to send mail to yahoo and hotmail (unable to send to internet).

Following is the my current configuration :-

Internal Sendmail (Linux) : 192.168.1.131 including FQDN DNS is sat.ctccomm.com (dns is working fine.) and mx record.

I had test using telnet 192.168.1.131 25 from client and from server. and set querytype=mx.(working fine.)

/etc/mail/acess
192.168.1.131 RELAY
192.168.1.0/24 OK
192.168.1.100 RELAY (windows client)

/etc/mail/local-host
sat.ctccomm.com

/etc/resolv.conf
nameserver 192.168.1.131
nameserver sat.ctccomm.com

ISP - Linux Router - 192.168.1.98

I want to send outgoing mail through linux router (internal sendmail forward outoging mail to linux router and router will forward to internet).

I tried to configure the say way but not able to send outgoing mail.

Can anybody help out me to resolve this problem.
