Relay access denied
We are using RHEL v4, we use POSTFIX / Squirrelmail in our mail server. We are able to send / receive all e-mails including external mails when we set incomming / outgoing mail server address using Local IP [192.168.1.101] of the mail server. we tried using MS outlook it works fine.
But we are NOT able to SEND any e-mail to recepients when we configured incomming / outgoing mail server address with the public IP or public host addfress [mailserver.abcd.com] of that server. We are getting Relay Access denied Error..
Since this mail server was configured by another administrator. Kindly let me know that is there nay configurations that prevents relay mail through Public address and allows through ONLY local address of the server for security resons.
