            Bug ID: 2982
           Summary: Writing logs to standard output
           Product: Exim
           Version: 4.96
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: wishlist
          Priority: medium
         Component: Logging

Exim cannot write logs to standard output. This creates some problems when Exim
is running as a container process.

I can read container logs when I run the daemon with `-bdf` option, but this
only works with pseudo-TTY allocated to the container. Unfortunately, I can't
collect logs from such containers.

I have searched the web for a solution, but everything that I found is ugly.
First, I can create symlinks to /dev/stdout and /dev/stderr instead of log
files. Another option is to run multiple processes in a container (xtail or a
syslog daemon). That is a wrong way, but even if I do, I need to write simple
process manager and in the case of the syslog daemon, I have to run it as root,
because it has to create /dev/log socket.


It would be great that Exim could write logs to standard output and we could
use someting like log_file_path = stdout in the config to enable this.
