Not able to send/Receive mail in local network
I have a small network with 10 clients and 3 servers ( assume s1,s2 and s3 )
All the clients are windows XP and the Servers are RHEL.
I configured sendmail in one of the server (s3) with RHEL 4.0.
It is working fine. Now i can able to send mails to my domain.
So, i created many mail users and we are using that now. All the windows clients can able to send and receive mails from outlook express.
we have one more office in another country.
There also mail is working fine.
The problem is ,
when we try to send mail from any linux machine ( such as s1,s2 ) it is giving error...
The error log is as below.........
