Indeed.  The solution is to put
  $|=1;
in an appropriate place near the top of the Perl script.

This applies to all of the similar reports from Raul Miller.

We'll leave it as it is; this message (which will be filed with the
original report) will tell people what the current status is.

Would the sendmail package maintainer please close this report when
the problem in sendmail is fixed ?  Thanks.

I haven't tried to reproduce this, but I suspect this may be
because of piping the output to tee.  It a pre|post script
prompts, the prompt gets stuck in unflushed output and the
script waiting for input looks like it's hung.  (the voice of
