SUMMARY: sendmail 4.1 vs. YP aliases

Restatement of the problem:

        This problem involves the "4.1 pre-release" sendmail running on
        SunOS 4.0.3 on assorted Sun-3 systems.

        After reading about the alleged security problems in Sun 4.0.3
        sendmail, I snarfed the 4.1 pre-release sendmail from Trouble is, the new sendmail doesn't find my YP
        mail aliases (it DOES find the aliases in my ~/.aliases file).

First of all, the quick fix that saved me: ( Richard L. Kruse II)

        You probably already know this, but you might wish to check
        your, and make sure it knows which alias file to
        check. You should check /var/yp/Makefile to make sure the two

        in /etc/
                # location of alias file

        in /var/yp/Makefile...
                ALIASES = /etc/aliases

Sure enough, I had OA/usr/lib/aliases in my Apparently
the 4.1 sendmail actually looks at the alias file, instead of just
checking with YP. Since all my clients use the same aliases, I just
moved the alias file back to /usr/lib and put symbolic links to it in
all the /etc's. Things work fine now.

Honorable mention to:

drk@Rational.COM (David Kaelbling)
amdcad!proton! (Scott McMahon)
        who both reported observing the same behavior I did. (Bobby Bodenheimer)

        who did NOT encounter the broken aliases on a 4/260. (Daniel Trinkle) (Stan Barber)

        who recommended I run sendmail 5.61 with Stan's patches.

        In case anyone else wants to try this, the source for sendmail
        5.61 is available in
        and the patches are in

halstern@Sun.COM (Hal Stern - SysAdmin)

        who asked me to keep him posted on what I found out (Sun IS
        listening ...)

Thanks everybody!
