Hello i am trying to use iRedMail and also xeams as the spam filter in front. I have the two installed and running on the same box i change the postfix server to listen on port 9267 then i installed xeams and it connects to localhost:9267 This all works fine. the problem is when i run a diag i get the error:: "Your server is an open relay, which means that any person from the Internet will be able to use your server to send an email to a third party recipient. Most common reason for this failure is that you have configured your email server to accept relay from the machine where Xeams is running. Since Xeams acts as a proxy server, every email that comes in from the Internet goes via Xeams and your server thinks that emails are coming in from a machine that is within your network rather than the Internet. How to fix it:: Configure your email server so that it does not accept relay from the machine where Xeams is running. " My question is how to i change the email server to not accept relays and if i do that how does the xeams talk to the iredmail server. Or is this an error or message that does not mean anything in my env. Any help would be greatly appreciated Thanks
