On a fresh install, courier runs, starts /usr/sbin/couriertcpd and courieresmtp, but when a connection is opened on port 25, syslog records: courieresmtpd: /usr/sbin/courieresmtpd: Permission denied The courieresmtpd file has ownership/permissions as follows: -r-xr-x--- 1 root root 1118352 Mar 27 23:11 /usr/lib64/courier/courier/modules/esmtp/courieresmtpd The courier parent process runs as user 'mail'. Changing either the owner or the group of the courieresmtpd binary to 'mail' fixes the problem, and mail receipt functions as normal.

Possibly related: I've also discovered that outbound mail suffers from a similar problem, because /usr/lib64/courier/courier/modules/esmtp/courieresmtp is also set read/execute for owner and group only, owned root/root. Mail from and to localhost delivers fine, but mail to off-host fails with "courieresmtp: Crashed child process [PID], while delivering to [domain]". "chgrp mail" on courieresmtp appears to fix the problem. Oddly enough, on another machine (previous incarnation of the one I'm building now), the exact same release and revision of the Courier package never had this problem. So the cause of the trouble must be external to the Courier ebuild (right?) but I'm not sure where else to look.
This is happening to me too. Doing a chgrp mail //usr/lib64/courier/courier/modules/esmtp/* did fix it for me. It looks like we have had this one before: https://bugs.gentoo.org/show_bug.cgi?id=181687
Another me too. It seems to be all the files within the modules/*/ directories that have changed from mail:mail to root:root. I was able to compare an affected server with one that hadn't been updated yet.
I saw and could reproduce this myself, however it was a bit tricky to debug into the problem. The root cause is that the courier Makefile checks for root rights by testing write access to /etc - portage prevents that. I'm currently trying to get patches up and running for courier upstream, so this should be resolved soon.
Together with upstream author Sam Varshavchik I was able to get a fix into courier's code. As it'd be a bit tricky to patch this, I've committed a snapshot release of courier now. Please test mail-mta/courier-0.68.2.20120626 which is now in ~, it should solve this issue.

Tested - working.
So seems this is fixed now.
