After upgrading the Tru64 UNIX operating system, you should perform
steps 5, 6 and 8 of the post-installation tasks for new sites, as
described in Section 1.6 ; i.e., remove
sendmail symbolic links, replace sendmail
with /pmdf/bin/sendmail and kill off any non-PMDF
sendmail processes, and start the PMDF Job Controller and
PMDF Service Dispatcher.
