Sure, include what you need.

I should perhaps mention that I'm on Fedora system, not Debian, and
Fedora uses "lib64" for libraries on 64-bit systems, but IIRC Debian
tends to use just "/lib". If that's the case, you might instead go
with:
shlib_directory=$PFIX/lib64/MAIL_VERSION \
Also be aware that the above choice means you get a fresh directory with
shared objects for each upgrade, and may want to manually prune older
versions if installing directly to the runtime location via "make
upgrade". If you're building a binary package, then upgrading the
package should remove obsoleted files.

The risk is that a system update might overwrite these with the vendor's
package. But if you're careful enough, and can configure the system to
blacklist the vendor package, the default paths may be fine. Your call.

On a virgin system there should not be an "existing sendmail", or at
most it is a symlink via "alternatives", which you'll override.
