Turns out that postfix was working just fine "out of the box", but the way I was addressing the mail was a problem. Once I had found /var/log/mail/info, all became clear. I had defined the server's IP address in the client's hosts file:
192.168.0.1 smtp.my.domain and was addressing mail: [EMAIL PROTECTED] On the server (so it could find itself): 192.168.0.1 server.my.domain was in the hosts file. With this setup, the info log shows me that postfix complains that this address causes it to loop back on itself. My solution was to make the server's hosts file read: 192.168.0.1 server.my.domain server and address the mail to [EMAIL PROTECTED] This works, but when the mail comes back it's origin is shown as: [EMAIL PROTECTED] so any attempt to reply falls into the original black hole. I have yet to find time to work on this. Tried changing the way addresses are rewritten using the webmin postfix admin stuff, but only managed to stop it working altogether. cheers Brian
