actually
     kill -KILL `head -1 /var/run/sendmail.pid`
because more than just the pid exists in the file.

some programs even need something like
     kill -KILL `sed 1q /var/run/sendmail.pid | awk '{print $1}'`
because the pid is only the first word of the first line.


you get the idea in any case...
