hi gurus

Hello gurus,

I'm facing a very strange problem with mail servers.
My problem is im able to send mails from these two
servers to any yahoo account or hotmail account with
no problem at all. But when i try to send mails
between these two servers, ended up only in errors as
"defer (-1): host lookup did not complete" from onde
server and on the other server "451 Temporary local
problem - please try later". I'm using exim 4 mail
server and im using Redhat Linux on both the servers.
This might look very silly for some of the gurus here,
but this is one is eating me up and i have to find a
solution. I searched  through the engines but unable
to fix this issue.

Thanks in advance and regards,
vinoth
