just a short question: Is Postfix able to handle both - IPv4 and IPv6 - at the same time in dualstack? I know that postfix can do that, i'm just wondering if i-mscp has included that.
With the dualstack listener file i was able to get dualstack for http(s). But i don't see how to get dualstack for postfix.
The main.cf in /etc/postfix shows only ipv4 in "inet_protocols". Also the "smtp_bind_address6" is empty.
I've found that file:
That looks similar to the dualstack apache listener file. Is it used the same way?
Would be good to know if dualstack for postfix is possible - and if yes: How.
Thanks a lot in advance for an reply!
