why does popen2 silently ignore IOError?

No IOError, I just meant that IMO, an IOError should have been raised.

This was what I was looking for.  It sounds like it isn't possible.

I thought what I wanted was simple.  I'm sending mail by opening a
pipe to /usr/sbin/sendmail -- if that fails for whatever reason (e.g,
sendmail program is missing) I want an exception raised with some
indication of the problem, instead of the current silent failure.

Is there any way to do this in Python?  Any example code to get me
started?

Graham
