Hi, It seems the default binaries don't have CDB tables compiled into them ? Now, I know Centos isn't Ubuntu, but on Ubuntu there is an optional package in the main distribution "postfix-cdb - CDB map support for Postfix". I can't find anything similar using "yum search", so I'm guessing that's not an option. Unless anyone else here corrects me otherwise, I'm guessing it's back to 'old-school' compile and install myself ? Thanks ! Tim
