I believe so - exim is being called from a perl script running as the
user stated in the log line thusly:
/usr/sbin/sendmail -oi -t
I get a spurious and unexplained
"Permission denied" error:
Does changing that to
/usr/sbin/sendmail -oi -t -v
give you any clues ?
"exim -v" doesnt give as much information as "exim -d" but should
be available as any user.
The protection on setuid processes means that while you can do this:
strace /usr/sbin/sendmail -oi -t
as an unprivileged user, the process will no longer be executed setuid,
and it definitely will not be able to access a bunch of files (such as
those giving it the credentials for the smarthost.)
The output of
strace -f -eopen,openat -o /tmp/exim.strace /usr/sbin/sendmail -oi -t
should be small and include the name of the file that cannot be read
(unless there is another unreadable file that stops exim reaching the
problem access).
