    I have had to change my postfix to disable IPV6 (getting bounces with lines like:
    [email protected]>: connect to[2800:3f0:4003:c00::1a]:25: Network is unreachable)

    clearly I'm not setup IPV6 properly so I've changed the inet_interfaces to IPV4 only.

    but - it raises the question how do I ENABLE IPV6 properly? (apart from changing 'IPV4' back to 'all')

    what do I have to have to get postfix to talk properly to google etc?

    and where do I get MY IPV6 address from??
    and how does ISPCONFIG incorporate it in the BIND files etc?

    my ipv4 address is

    oh - got the ISPPROTECT problems under control still wish I could find a reference for what a named-malware that you report actually DOES.
    is there not a database somewhere I can look it up and see what the nasty is up to?

    thanks as always

    the IPv6 address is assigned to you by your server provider. So if you did not get one from them you cannot set up v6 on the server.

    @ISPProtect: There are so many malware types that it will hardly be possible to list them all in a database. We might build one of the most important entries, but not for now.

    ok I'll hit verizon FIOS to provide me with some. it turns out that restricting postfix to ipv4 breaks mailman! so I have go to back to all protocols accepted, and I need to fix the ipv6 problem.
    any tutorial on how to install an ipv6 on a running system?

    Are you sure about that? When postfix is listening to IPv4 only and the domains have no IPv6 records then I don't see how mailman can be affected by IPv4 only.

    basically, you will have to edit the network config file and add a section for IPv6. But this differs for the different Linux distributions and might even differ a bit for the network setup used by your ISP. Best is to search for a IPv6 network config guide on the internet for your OS and OS version and to do that search for your ISP as well, it might be that they provide some instructions specific to them.
