You might see what disabling ident does to the system. In my
experience, if you disable ident, it doesn't break things like
sendmail. Comment out the line in /etc/inetd.conf, then restart inet
and see what happens. If your Notes communications (or anything
important) dies, reverse the procedure and try the next thing. Let
us know.
