I know this is not strictly a courier code issue but I'm trying to track
down a permissions issue and from this strace I am getting...
setgid(1) = 0
getuid() = 0
setgroups(1, [1]) = 0
setuid(1) = 0
chdir("/usr") = 0
chdir("/var/lib/courier/tmp") = 0
[... ending with ...]
sendto(3, "<19>Jan 2 19:05:47 submit: Permission denied", 45, MSG_NOSIGNAL,
NULL, 0) = 45
unlink("145172/1451725547.16796.goldcoast.org") = -1 EACCES (Permission denied)
but there is nothing in /var/lib/courier/tmp.
My question; does that setgid(1) and setuid(1) mean to change to the
uid:gid of 1:1?
That is daemon:daemon on Debian systems whereas it should be 114:117
on my system for the "courier" user. If so then it would explain why
/var/lib/courier/tmp owned by courier:courier can't be written to by
a program changing to daemon:daemon.
Which probably means the packages I am testing are built with some kind
of internal daemon:daemon permissions whereas all external files are
given courier:courier, ie;...
./esmtpd:MAILGROUP=courier
./esmtpd:MAILUSER=courier
