It appears that this will do the job for me.
It appears I was too optomistic. It's not working. Here's the error from the exim log (originally all one line - wrapped here for clarity): 2000-06-11 14:13:02 131CEI-0002xP-00 ** |/home/picuser/picadmin/message_handle.sh <[EMAIL PROTECTED]> D=userforward T=address_pipe: Child process of address_pipe transport returned 1 from command: /home/picuser/picadmin/message_handle.sh The local username on my box is picuser, and the shell script I'm trying to write is message_handle.sh > > Fwiw, you could use "exec cat" instead of "cat" if you needed the shell > > to persist after the cat invocation, but that's a different story. > > I'll keep that in mind, but for this application I don't think it'll > matter.

I've also tried the: cat /dev/stdin > message.txt that someone else was suggesting. That gives the same error in the exim log. But I think I've finally found a possible solution - I wrote a very small program in C that reads from stdin and writes to a file. And that does work. So I guess I'll be doing this in C instead of a shell script. That's okay though - I could use the practice with C.
