Re: How to keep several Postfix installations in step with each other?

ut 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/
