Up to now, we've been running Postfix 2.3.3 that was installed on a number of CentOS 5.5 production servers with a simple "yum install postfix"
We want to run an updated version, so I compiled 2.7.2 from source using the information at http://postfix.wl0.org/en/building-rpms/ When creating the postfix.spec file, the only additional option I explicitly added was: export POSTFIX_PCRE=1 Everything seemed to go fine and the CentOS 5.5 test box I built and installed it on appears to be sending test mails as expected. However, I want to compile in the same options that are included in the "default" 2.3.3 version that we're running on our production servers. However, I couldn't find a postconf option in the docs to show which options were included at compile time. Is there a command that will show them, or a list somewhere that shows which ones were included in Postfix 2.3.3 installed by yum on CentOS 5? Thanks in advance, Steve
