Seconded on using a config management package. Saltstack is a good choice, too. (Your case is simple enough, though, that shell scripts that copy from a private git repo is also reasonable. That avoids the learning curve of something like salt/ansible/puppet/etc.) You have one config (on your desktop) that receives and passes to an MDA and that also sends to a smarthost. You have on config (maybe on multiple machines) that sends to a smarthost but doesn't receive, not even if you cc yourself. So I'd start by copying your config to your laptop, then just ask yourself what you need to change so that mail to "local" users is sent to the smarthost. Once mail to yourself goes to smarthost, you're probably almost there. -- Jeff Abrahamson +33 6 24 40 01 57 +44 7920 594 255 http://p27.eu/jeff/ http://transport-nantes.com/
