I am setting up a mail server for a church and postfix seemed to be the answer it has apachelike cconfiguration, its free and its supposed to be good. I have had nothing but problems with it and I was wondering if anyone else might have an idea why. I am running a maching with Mandrake 8.1 and the SMP kernel. Once I downloaded the source and unzipped it and ran "./INSTALL.sh" it prompted me a bunch of times for a directiry structure of how to set up the server. The default values were displayed and I just hit enter. After the prompting was over with it gave an error saying "../bin/postconf" is not there. I checked the bin directory in the install directory and there really was nothing there. Would anyone have an idea? I decided to reinstall mandrake with postfix as a preinstalled package. When I run it and send a file to a user on the server (ex. root@192.168.0.2) it gets returned saying: This is the Postfix program at host northumc.org. I'm sorry to have to inform you that the message returned below could not be delivered to one or more destinations. For further assistance, please send mail to If you do so, please include this problem report. You can delete your own text from the message returned below. The Postfix program : mail for 192.168.0.2 loops back to myself I went into the "main.cf" file and uncommented the following lines: ----Start of Paste------ myorigin= $myhostname myorigin= $mydomain inet_interfaces =all inet_interfaces =$myhostname inet_interfaces =$myhostname, localhost -------EOF---------- When I try to do "./postfix reload" it gives the following error: "postfix: fatal: parameter inet_interfaces: no local interface found for 64.255.145.175" I cant figure it out. The Linux box is behind a netgear fa314 gateway router, it has a 192.168.x.x address, the only interfaces are "eth0" and "lo" and that IP is not that of the router. That error only occurs when I uncomment the bottom two of the "inet_interface" lines in the config file. Any help would be greatly appreciated.

I am also having the same problem with the loopback error message. I just installed Mandrake 8.2, configured postfix via Webmin, and can't seem to receive any mail. Can anyone help us?

Fixed the error via Webmin. You can also find the problem area to fix in the /etc/postfix/mail.cf file. What I did was change the "domains to receive mail for" option from local computer or local host to whole domain. Worked like a charm! I don't know if this will work for you but I hope it helps. If you know how to work with the vi editor or some other editor, you can find the parameters and edit them by hand if you wish, but I don't remember how to save a file with vi *sob* so I had to resort to webmin. And btw, webmin comes built in with mandrake so you should have it unless you turned it off. try typing this in your browser if you can't figure it out: https://127.0.0.1:10000 good luck!
