What are you trying to achieve with sendmail, and what Unix are you using, I do not see a -i option for sendmail on the manpage I am looking at?
I've come to realize that the sendmail package isn't installed.

It is just a symbolic link to postfix set up by installing bsd-mailx.

I have changed my crontab to

Code:
MAILTO=""
#m      h       dom     mon     dow     command
*       *       *       *       *       /home/woodnt/bin/test_cron > /dev/null 2>&1

Check out this ps output after doing that:
