Hi Walter, I realize that 2.3.3 is the version of Postfix that is installed by the default CentOS repos, but as already recommended on this thread, you may want to consider the jump to a newer version. I recently upgraded directly from 2.3.3 to 2.8.0 on three of our CentOS 5.5 boxes, and wrote a detailed how-to here (it's a very painless process that takes less than 5 mins and keeps all your existing config files intact): http://stevejenkins.com/blog/2011/01/building-postfix-2-8-on-rhel5-centos-5-from-source/ >From the looks of your config, you'll need to modify the make makefiles command from my how-to slightly to compile in MySQL support, but if you have it running with 2.3.3 currently, then you probably already know how to do that. :) Best, SteveJ
