Hello, I just configured postfix so that it uses MySQL database to store virtual domain and user info. When SELinux is enalbed, postfix fails to connect to MySQL. Below is an example error from the mailog file. postfix/trivial-rewrite[4753]: fatal: mysql:/etc/postfix/mysql_virtual_alias_maps.cf(0,lock|fold_fix): table lookup problem When I turn off Selinux, the problem does not appear. How can I configure Selinux to allow postfix to connect to MySQL? I am using CentOS release 5 (Final). I have installed the postfix and mysql-server packages from CentOSplus repository. The server is located in a remote location and GUI is not installed on it. I appreciate any help, Regards, Sudheer
