Thank you one and all for the replies to my problem:

the question was:

>I just installed 4.1.2 and all of a sudden sendmail is reporting that
>all users are unknown. Is there some problem with the 4.1.2 sendmail ?

>Situation is SPARC 2 master NIS server with two SPARC 2 NIS slaves and
>two SPARC 1 clients plus a bunch of PC-NF pc's.
>I did not do anything fancy, just installed 4.1.2 and rebooted the
>machines and tried to send mail and I get "user unknown".

And the answer is:
SUN made a boo-boo. According to bug reports just in at SUN technical
support, they attempted to "fix" sendmail and broke it. So there is now
a priority 2 ( whatever that is ) bug in sendmail.

The workaround:

After installing 4.1.2 you can either:

1) After booting the system, kill sendmail and restart it, at which
   point mail will work just fine.

2) you can restore the 4.1.1 sendmail stuff from your backups of the
   previous system files ( you did make a backup before installing 4.1.2
   didn`t you ? ).

3) remove /etc/sendmail.fc, do not recreate it then reboot.
   This straight from SUN, but doesn't seem like a viable alternative
