The postfix ebuild creates a new user, postfix, with home folder at /var/spool/postfix, thus: > pkg_setup() { > # Add postfix, postdrop user/group (bug #77565) > enewgroup postfix 207 > enewgroup postdrop 208 > enewuser postfix 207 -1 /var/spool/postfix postfix,mail > } Which we can confirm from /etc/passwd: > famine@gentoo ~ (0) $ grep postfix /etc/passwd > postfix:x:207:207:added by portage for postfix:/var/spool/postfix:/sbin/nologin Which results in postfix owning the folder: > famine@gentoo ~ (0) $ ls -ld /var/spool/postfix/ > drwxr-xr-x 16 postfix root 424 Dec 18 00:33 /var/spool/postfix/ However, postfix itself doesn't like this arrangement and complains about it to the syslog at every boot: > famine@gentoo ~ (0) $ sudo postfix check > postfix/postfix-script: warning: not owned by root: /var/spool/postfix/. So - the program says this folder should be owned by root, but the ebuild creates the postfix user with its home folder here (and hence postfix ends up owning it). These two things are in conflict - to have a user's home folder not owner by that user is non-sensical (and I'm nervous therefore to change its ownership from postfix:root to root:postfix). The ebuild probably needs to be updated to create a structure that postfix is happy with (perhaps creating /var/spool/postfix/home as the home folder?).
Please check postfix-3.3_pre20180107. Leaving the bug open for now as postfix-3.3 releases are masked
