replaced with the new version in sendmail's distribution, vacation and
the necessary libraries (libsmdb and libsmutil) were changed so they
were always compiled. This broke people who didn't checkout
src/contrib/sendmail/. I don't know if it's best to think of NO_SENDMAIL
as no sendmail sources available or no sendmail binary. It is now the former.
Also, remove the sendmail chapter from System Managers Manual (SMM) if
NO_SENDMAIL is defined (for similar reasons -- source not available).
