Have you considered the security implications of such a move?

There's no way to do this currently, except for symlinking the actual
sendmail-compatible binary (whatever it is in your distro) to the
predefined path (preferably, to the place defined by _PATH_SENDMAIL
in your /usr/include/paths.h). In fact, that's what all distros that
I've ever seen do.
