The problem is that Exim, by default, does not run pipe commands under a
shell. It splits the line up info components by itself, and runs the
command directly. This provides improved security. There are two things
you can do:
(1) Tell users that if they want to run a pipe under a shell, they must
explicitly set one up in their pipe commands. In other words, instead of
|IFS=' ' && ...
you have to say
|/bin/sh -c "IFS=' ' &&
Alternatively, set up the command so that it isn't in the form of a
shell command.
(2) Wait for the next release of Exim, where there is a "use_shell"
option on the pipe transport to cause it to pass the command to /bin/sh.
