I have something like this in my Exim conf:
# a customized bounce handler my_handler: debug_print = "R: ..." driver = redirect allow_defer allow_fail log_fail_output data = |/path/to/cmd pipe_transport = address_pipe file_transport = address_file no_more
The conf and the command both work fine. But if there's an error, I only get this line to mainlog:
[...] Child process of address_pipe transport returned 1 from command: /path/to/cmd
How can I log the
stderr output of the command? (That is, the actual error message.) I looked at
log_fail_output but that seems to be only for
I'm running Exim 4.71 on an Ubuntu machine.
