SUMMARY-Sendmail on a Standalone System

I mananged to answer my own post after much experimentation and
a call to SUN.

The orginal problem was that I could not get SUNs Sendmail to work
reliably on a SUN Sparc 20:

SunOS 5.4 Generic_101945-27 sun4m sparc

which is sitting by itself on one of our campuses networks- i.e. it
has no clients- it is the mailhost, mail server, relay host etc- the
rest of that network is all PeeCees.

The solution was to use as /usr/lib/sendmail and
use as /etc/mail/ where has the following

(line 26) Dj$m { Comment out
(line 28) #Dj$w.$m { UnComment out

(line 78) Dm { Dm"DOMAIN.NAME"

(line 400)
# Replace following with above to only forward "known" top-level domains
R$*<@$*.$+>$* $#$M $@$R $:$1<@$2.$3>$4 user@any.domain

{comment out this line
# if you are on the DDN, then comment-out both of the the lines above
# and use the following instead:
#R$*<@$*.$+>$* $#ddn $@ $2.$3 $:$1<@$2.$3>$4 user@any.domain

{Uncomment out this line

Another part of my problem was that the IP for this node did not
have the correct DNS records. I could do forward lookups ( or
was it inverse?! ) but not inverse lookups ( or were they forward?! ).

Because of some problem with mail routing, my initial post did not
make it to the group until 2 days later, at which time I had already
worked through the problem.

Thanks to Steve Hodnett at SUN for the above rule changes!
