I am setting up a second outside server at Linode with CentOS 6 for my wife's new office. One of the surprises was configuring the postfix MTA (mail transfer agent) and mailman for IPV6.
The linode/centos virtual has IPV6 enabled out of the box. After much inept bungling, debugging, and gnashing of teeth, I realized the reason that postfix was not accepting messages from the mailman list software was that they were coming from IPV6 localhost [::1] rather than IPV4 localhost 127.0.0.1 . So instead of a main.cf file containing: mynetworks = 127.0.0.1, ... I needed to use: mynetworks = [::1], 127.0.0.1, ... And yes, the square brackets are required for postfix to parse the address. There is nothing about IPV6 in most of the older postfix documentation, including the Kyle Dent book from O'Reilly. The world needs a much better, example/cookbook oriented postfix book. With a glossary. And interpretations of error messages. Some of us (including all Mac OSX users) don't have the time to become postfix virtuosos for two or three machines.
