Email Server Locally Relay
Hi, I'm facing a problem where I want my email server to relay to each other.
I've 3 email servers, 1 is running on Linux Qmail, 2 are running on Sun Cobait email server.
3 server are running on same host name, and 2 of the Sun Cobait can talk with each other locally. This is setup because of 3 branches of same company, running at different country.
For Qmail, I'm not manage to link it up together to another 2 branches. we can send emails to qmail server, but qmail server cant email back to Sun Cobait email server....
How to enable QMAIL replaying locally, intranet.....?
