 Well, I think there _is_ need for changing something because otherwise
 /usr/sbin/sendmail points to a not existing/stale /usr/sbin/mailwrapper
 in case NO_MAILWRAPPER is used.

 So you suggest that if NO_MAILWRAPPER is specified, the
 usr.sbin/sendmail/Makefile should set a symlink from /usr/sbin/sendmail
 pointing to /usr/libexec/sendmail/sendmail?
 
 How about the etc/Makefile? Is the modification okay so there is no
 unneeded mailer.conf hanging around if NO_MAILWRAPPER is specified?
