postfix with multiple mail servers, no DNS
 

Ok,
Here is my issue. I have a postfix server installed, I need to be able to send email to two different mail servers, in two different domains and ip addresses(obviusly). I dont have DNS. I cannot do an nslookup on these servers. I can send mail via port 25 to them. How do I configure postfix in order to send mail to multiple mail servers outside my domain which I dont have DNS communication with? i.e.


send mail from mail.myserver.com to

mail.vader.com
mail.luke.com

sending to mailbox user1@vader.com
sending to mailbox user2@luke.com

i.e.

echo test | mail user1@vader.com

I have there FQDN and Ip of both different mailservers

Add the names of the other external servers to your /etc/hosts file then add the name of your server to the other two external servers' /etc/hosts file.
