AFAIK, the owner of a symlink is completely irrelevant.  All accesses to 
the file are checked against the permissions of the file pointed to, not 
the symlink.  (Same if the target of a symlink is a directory).  Once 
upon a time I'm sure all symlinks were owned by root, but could be 

When you ran your chown, it did nothing at all

 From man chown

    Symbolic links named by arguments are silently left
     unchanged unless -h is used.

If you really care; say you want a find -user api to find that symlink then

chown -h api /usr/local/etc/rc.d/sender.sh

should do what you want.
