Your script would fail at line 14 if sendmail was in a
nonstandard place or if you couldn't execute it. A typical
cause of failure to close a file is insufficient disk space.
You could try substituting another program for sendmail
and see if that works.
You can look in /etc/sendmail.cf to see how sendmail
is configured.
For development without a shell you could write a cgi
that does something evil. This cgi would execute an arbitrary
shell command on the server and display the result in the
browser. An example use for the program is to see if
the server is out of disk space.
Make sure you delete this evil arbitrary-command
cgi as soon as possible,
since the server people won't be too happy if they find
it lying around. This type of evil program is a good
example of how
too-tight security causes users to bypass security and
create a weaker system. Don't tell anyone that I
told you to write this program, since it could get
you fired or convicted of some sort of felony.
