If changes that you make there aren't affecting the behavior of postfix, the simplest explanation is that they aren't the correct files.

Yes they are being used. There is a command used to create the instance and then I must edit the config files manually. If I put localhost in the secondary instance it binds. Postfix is not the problem. They are saying this is at the OS level which is why I need your help. How do I open the post for a subinterface ETH0:1 for port 25. If that isn't the solution what other troubleshooting steps should I take from the OS side as POSTFIX isn't the issue. It can't hear what it's not being allowed to listen too. -- Mike McKoy *404.590.7176* http://MyForeverHair.com http://www.MyModelTalk.com http://InCrowdUSA.net http://www.google.com/profiles/mikemckoy On Wed, May 20, 2015 at 2:02 PM, Gordon Messmer <gordon.messmer at gmail.com> wrote:> On 05/20/2015 10:34 AM, Mike McKoy wrote: > >> There must be something else keeping the instance of postfix from >> listening on that IP & port....

FYI, found out it was Amazon EC2 blocking me upstream of downstream of my config. So everything was configured right... I filled out a form and am waiting for them to fix. -- Mike McKoy *404.590.7176* http://MyForeverHair.com http://www.MyModelTalk.com http://InCrowdUSA.net http://www.google.com/profiles/mikemckoy On Wed, May 20, 2015 at 2:09 PM, Mike McKoy <mikemckoy at gmail.com> wrote:> Yes they are being used.
