Good plan.

You want to read the man page for chflags, it explains why this won't
work.

With respect to the person who answered you previously, there is an
easier way to avoid your problem. Instead of changing the makefile in
/usr/src/usr.sbin/sendmail you want to change the one in
/usr/src/usr.sbin. Change to that directory, then cp Makefile makefile.
You don't need to .cvsupignore this file since cvsup ignores files it
doesn't know about by default. Then, use your favorite editor to modify
makefile. You want to remove the reference to the sendmail directory.
There is only one in this makefile, but if you use this method for other
things there might be more than one.
Now when you do a make world, the whole sendmail directory will be
ignored so nothing in it will be built. I have a little script that
checks the $Id of the makefiles I've modified so that if any of them get
updated after a make world I can merge the changes in by hand. Here's
how your entry would look, plus some stuff at the end you might find
helpful if you make the world often.

There may be easier ways to do this, but this works for me. :)
Good luck,
