it means exactly what it says. that postfix isn't allowing you to relay through it. that means that: the request is coming from a non-local ip address for a non-local domain. if it is supposed to be a local domain you need to fix postfix to make oz.net, post.net and mattyt.net local domains. if they aren't suppoesd to be local domains (eg. they are hosted on a different box) then you need to add the ip address that mailman is trying to send to to the postfix's list of local ip's (normally maintained in /etc/postfix/access i believe). adam.
