smtp-AUTH :relay access denied

I have solved the problem with smtp -auth. ( relay access denied ) and thought i would share my configuration the with those who are facing similar issues My system is FC4 and i wanted a basic requirement of system users on my mail server ( only one domain ) . setting up of postfix in this case is pretty easy but smth-AUTH as major problem. Here are some of my tips and configuration files i sued to authenticate users through PAM instead of the /etc/shadow . { note: for to users authenticate r through /etc/shadow you would need to allow postfix have read permission to the /etc/shadow file , which would be a security risk by default /etc/shadow is 400 }

the testsaslauthd is a command to check is system user authenticate testsaslauthd -u testpostfix -p testpostfix

vi /etc/sysconfig/saslauthd # Directory in which to place saslauthd's listening socket, pid file, and so # on. This directory must already exist. SOCKETDIR=/var/run/saslauthd # Mechanism to use when checking passwords. Run "saslauthd -v" to get a list # of which mechanism your installation was compiled to use. MECH="PAM" # Additional flags to pass to saslauthd on the command line. See saslauthd(8) # for the list of accepted flags. FLAGS=
