Temat: [Exim] pipe_as_creator not piping as creator
Hello again,

I have the following transport in my exim configuration file to pipe a
message through tmda:

tmda:
driver = pipe
pipe_as_creator
command = "/usr/local/bin/python /usr/local/tmda/bin/tmda-sendmail"
return_path_add
return_fail_output


As I mentioned yesterday this gets called from a router based on certain
conditions in the mail. No prob there.

The problem is the pipe needs to be run as the user who submitted the
message, which my understanding is the pipe_as_creator option provides.

However even though the logs appear to say the pipe is being called by the
user "tmj" (that's good) the uid/gid corresponds to the user "nobody"
(that's bad), which of course causes it to fail. Here's a snippet from a
d9 delivery output:

post-process tmj@??? (7)
LOG: 0 MAIN
** tmj@??? R=tmda_outgoing T=tmda: Child process of tmda transport

Did I not write the transport correctly or does anyone have any idea why
this would be behaving like this? Exim runs as its own user "exim". (This
is OpenBSD 3.0 if that matters.)

Thanks for your assistance.
