SUMMARY: 4.1.3 sendmail problem

Sorry this SUMMARY is so late. Apparently this problem is very well
known and is a FAQ.

My original query follows at the bottom of this mail. The overwhelming
response was that the sendmail invocation in /etc/rc.local should be
moved down in the /etc/rc.local file to a point after the ldconfig
lines. The sendmail needs the shared libraries but can't have them
until ldconfig runs and so starting it before ldconfig will cause
problems. Killing it and restarting therefore works because the second
invocation is done after ldconfig has been started.

Some other suggestions were:

        get patch 100377-05
        don't use frozen configuration files (sun recommends against it?)
        possible NIS race condition

If you want the full set of unadulterated replies, send me mail.
