Hi this is a strange error. I just had the chance to reinstall postfix from latest snapshot source on a new centos 7 server.
When running postconf -n I was getting various errors relating to unused parameters from mysql map configuration files. This is an example of the message: postconf: warning: mysql:/etc/postfix/mysql-domains.cf: unused parameter: user=xxxxx Such messages were repeated for various parameters. These same configuration files work fine on another server (running the same version of postfix). I realized it was something to do with the compilation process. I have to admit that I never pay much attention to the detailed output of the compilation as long as it ends in success, but going back over the output I found several of these warnings: extract_cfg.sh: line 74: m4: command not found With this clue I noticed that extract_cfg.sh was not extracting all the keywords that could be used in mysql map type configuration files due to the fact I had forgotten to install m4. I was wondering if it might be wise to make m4 a mandatory prerequisite, without which compilation would fail. John
