If I run a docker image with the mesos containerizer and altering the dovecot config mentioned here[1] I think the root detection is incorrect because it looks like dovecot is still thinking it is root. I still get errors like:>> log(829825): Fatal: We couldn't drop root group privileges(wanted=10053(dovecot), gid=0(root), egid=0(root)) Why does it want to drop to root, if we are not even running as root?>> Error: service(ipc): chown(/var/dovecot/login/ipc-proxy, 91,4294967295) failed: Operation not permitted Why does it want to chown, when it is not root? pop3-login: Fatal: setgid(101(dovenull)) failed with euid=10053(dovecot), gid=10053(dovecot), egid=10053(dovecot): Operation not permitted (This binary should probably be called with process group set to 101(dovenull) instead of 10053(dovecot)) [1] https://wiki.dovecot.org/HowTo/Rootless?action=edit&editor=text
FYI, I am building on alpine 3.10 and 3.11 I am getting this build[1]
error. I think these header files of dovecot are not correct. Or are
they?
I changed line 35 in /usr/include/dovecot/str.h
from
str_append_max(str, cstr, max_len);
to
str_append_max(str, (const char *)cstr, max_len);

const void*, size_t)':

I don't remember if that means the removal made it into 2.3.11, but it will definitely be gone from 2.3.12. Jeff. -- Si hoc legere scis nimium eruditionis habes.
