I'm not aware of any file editing method in Puppet that will modify multiple files as part of the same resource. The usual approach would be to create multiple resources, one for each file, and then cause each resource to notify the postfix service to restart. Puppet's smart enough to only restart it once. As far as setting up the files the way you want them, if you need to edit the files in place Augeas is your only built-in option. You can also do hacky things with exec but it's not pleasant. Most folks don't edit in place, they replace the file with known good contents. For that you can use templates or something like puppet-concat (a third-party module that allows you to build files from fragments).
