SunOS 4.0 and up sendmails check whether or not the /usr/spool/mail
partition is mounted and if it is, forward the mail to system it is mounted
from. I have modified the IBM sendmail.cf here to forward mail to a
system that can resolve any non local mail and itself receives all
the mail from the other RS6000 systems. There are also problems with
file locking if multiple sendmails or /bin/bellmails are trying to write
the same file at the same time. These are gotten around if the mail
is always forwarded to one system which installs the mail. The IBM
sendmail also will not send mail to any machine in the Austria country domain
.at due to the way they handle spaces in the configuration file. The 
.at gets changed into an @ which is will of course be unresolveable.
