    Set up an OpenVPN server with a firewall that works as follows: There must be administrators who are allowed access to all nodes. There should be pools of different sites, and nodes included in them, each of which has its own VPN certificate and VPN address. Within these pools, access between nodes is open but can be restricted if needed. There are also companies that can combine pools of several sites. In other cases, there is no direct connection between the pools of different sites. Pools of organizations and their nodes should be pulled automatically from the JSON file, and the rights to the pool should be automatically issued to the node based on the contents of this file, while administrators, as mentioned, should always have access to all nodes. JSON example: { "sitenam...

    I have a Debian Squeeze system running Dovecot 1.2.15 Postfix 2.7.1 PostgreSQL 8.4.22 Saslauthd 2.1.23 I need you to migrate the 47 domains (there are 21 additional domains that are mine, that are just aliases; a few of the 47 domains are just aliases as well) with 612 email accounts to an up-to-date Debian (stable) system. The source system uses mbox format and the new system will use maildir, so the files can't simply be rsynced, but need to be copied via imapsync or a similar tool. It will probably be the best idea to move one domain at a time and evaluate whether the users are happy, etc. Once a domain or two is successful, the rest could go faster. It will probably make sense to do an initial sync and make sure that it looks pretty good, and then I'll turn down the TTL ...
