Exactly. There's also a problem later on with the bounce, though. You can tell postfix to accept the default address generated by your MUA and rewrite it to the correct address. This is good for servers that just have to send out mail (mail from cron and things like that), since rewriting is simple; there's just one domain. This is what you seem to have tried to do in the logs above, but usually the machines that I configure like this send all their mail to a smarthost . . . You should configure "myorigin" in the configuration file, details at http://www.postfix.org/BASIC_CONFIGURATION_README.html You can configure postfix to accept only properly qualified addresses, and configure the program that you used to inject the mail to use the proper address. This is good for ISP mail servers that serve a lot of MUA clients (Thunderbird, Outlook...) that have different domains. Otherwise, you can do something more complicated, but you'll need to read http://www.postfix.org/ADDRESS_REWRITING_README.html Hope this helps.
