I added the following line to ruleset zero in my sendmail.cf file:

    R$*<@NoMail>    $#error$@67$:user cannot receive mail    "67" == EX_NOUSER

(be sure to double-check the value of EX_NOUSER in /usr/include/sysexits.h)
and lines similar to the following in my aliases file:

    olduser:olduser@NoMail

This results in SMTP exchanges such as:

    220 Logicon.COM Sendmail 5.61/6.03 ready at Wed, 7 Mar 90 10:26:05 -0800
    HELO Red-Baron.Logicon.COM
    250 Logicon.COM Hello Red-Baron.Logicon.COM, pleased to meet you
    MAIL FROM:<JEFF@Red-Baron.Logicon.COM>
    250 <JEFF@Red-Baron.Logicon.COM>... Sender ok
    RCPT TO:<tony@Logicon.COM>
    554 tony@NoMail... user cannot receive mail
    QUIT
    221 Logicon.COM closing connection

This is better than Karl's shell script because the body of the
message is not transmitted.  Note that the error code is 554 instead
of 550 as it really ought to be according to RFC 821; I'm not sure how
sendmail might be changed to correct this.
