I have a postfix on a server and I have a webserver with a application that needs a stmp server to send out emails.
When I run a test from the webapp to the postfix server trying to send a email to a outside address I got:
A test email has not been successfully sent to the email address firstname.lastname@example.org
: 572 <email@example.com>: Relay access denied
If I use a email address based on the postfix server it will send the email to that localize address
I need to have this postfix server configured to relay mail to outside addressed and anyone give me instruction on the configuration of the server to do this.
