Webmin as shipped will use Yum on CentOS to handle software management
(other than Perl modules).  From the way the information is presented
by the OP it seems likely that the default method is used in this

The error is this:

>> unknown user name value: postfix

You are missing the postfix user id in /etc/passwd.  If that user id
is missing then it is likely that your install procedure did not
complete properly.  I would suggest using yum remove post followed by
yum install postfix issued as the root user from the command line.
