Dear Robert Moskowitz
The link *
http://campworld.net/thewiki/pmwiki.php/LinuxServersCentOS/Cent6VirtMailServer
* you suggested is working great for me so far.
At one point it says
Configuring Postfix
Here we go with more config files. You'll have to be sure to change some
settings to match your host. The config files will have sections commented
out. Don't worry about it. These sections are for spam/virus/sympa
configuration. Just copy and past to create the config files. What ever you
see here replaces what already exists.
The main postfix config files.
/etc/postfix/main.cf
When I checked, I did not find any folder postfix in my /etc path. Even I
searched the whole machine, I did not get main.cf anywhere.
Does it mean that I have done some mistake somewhere in earlier steps.
Even, in main.cf file given in above link has an entry as below.
*daemon_directory = /usr/libexec/postfix*
But in my machine I do not see any postfix folder in path /usr/libexec.
However I found /var/lib/postfix folder. So should I use
/var/lib/postfix instead of */usr/libexec/postfix*.
Please guide me.
