I am setting up a mailserver with Postfix. While configuring it, I see the following values in main.cf. What causes these entries to appear?

   manpage_directory       = /usr/share/man
   sample_directory        = /usr/share/doc/postfix-2.3.3/samples
   readme_directory        = /usr/share/doc/postfix-2.3.3/README_FILES

I looked it up and this is in the manpage.

readme_directory (default: see "postconf -d" output)

The location of Postfix README files that describe how to build, configure or operate a specific Postfix subsystem or feature.

    ... Anyways I dived into the postfix src and found out why, but because I cannot answer this question except this comment. I will just say it belongs to legacy code.

  • They seem related to /etc/postfix/postfix-install but there aren't any clear reference about their relationship with the working daemon in the docs.
