Except if that if /usr/sbin/sendmail.exe did exist in the first place
(not a dangling link) then cronlog would not have been linked,
for the same reason:
 [ -e /usr/sbin/sendmail -o -e /usr/sbin/sendmail.exe  ]

and thus the rm -f would not do anything except possibly remove
a dangling symlink. I still don't understand what happened.
