You can't pipe at both ends in perl - at least not without serious pain.

You may be able to do this by using IO::Pipe to set up a pair of pipes,
fork() and attaching the pipes to stdin/stdout of the subprocess, exec-ing
exim, and talking to the pipes in the parent process - you probably need
IO::Select to make sure you don't get yourself knotted.

The easy solution is more likely to be:-

    open (CMD, "| exim -d0 -bh $ipaddr 2>&1 >/tmp/filespec");
    print CMD "various SMTP bits"
    close CMD;
    open (CMDRES, "</tmp/filespec");
    (read and process earlier command output)


This would be pretty easy to do in expect....
I don't know of a decent easily available perl expect module yet.
