I am using Ubuntu Server 13.04 on my mail system. I am just setting the Postfix and Amavis. In every config for communication I am using as IP address to pass mails to amavis. When I look to the logs its still trying to connect to Amavis with my eth0 IP address which is connected to the internet. I dont want to allow this IP address in the configs. Is there any way how to tell Ubuntu to use the instead of my internet IP address? I dont know why this is happening. Thank you.

Edit: More info

This is what I set in postfix

content_filter = amavis:[]:10024 

and  inet  n  -       -       -       -       smtpd
  -o mynetworks=

Also this is what I have in /etc/amavis/conf.d/50-user:

@inet_acl = qw( );

But when I try to receive a mail, in the logs there is:

 amavis[29607]: () (!)DENIED ACCESS from IP, policy bank ''

where is my IP address of eth0 interface.. Why its not accessing it with but with eth0 IP address? I think I am missing something and this might be just how it works.. I am just asking if there is any explanation or possibility to change this. Because now I always have to add my IP address to inet_acl and the subnet mynetworks.. Thanks.

Show us exactly what is happening and exactly what you have configured. – Michael Hampton Oct 21 '13 at 17:24
I have just added more info.. Hope it will make more sense what I mean.. Thank you for the reply @MichaelHampton – InToSSH Oct 22 '13 at 11:28

Check for inet_interfaces option in Postfix. I suppose Postfix should explicitly bind to use in output communications.

Thank you for suggestion. Anyway since I have to use both and my inet address its not gonna make any change.. I have tried it and its doing still the same. – InToSSH Oct 22 '13 at 20:18
