-You don't have to install mail.local to run the new version of sendmail.
-Many versions of /bin/mail take a "-d" flag or do local delivery already.
-In particular, mail.local is largely specific to 4.4 BSD, and will not
-be easy to compile elsewhere. It was written by Keith Bostic, not myself,
-and was not intended for the "general case".
+PLEASE DO NOT MAKE THIS AVAILABLE ON PUBLIC FTP. Since it is still an
+early release, I'd prefer that people get copies directly from Berkeley
+to make certain that they have the most recent version. This isn't
+an attempt to limit access, just to make certain that everyone is able
+to keep up. If you got this version from anywhere other than direct
+from Berkeley, check the machine FTP.CS.Berkeley.EDU, directory
+/ucb/sendmail for the latest version.
