If you're using spamass-milter from Extras, the following should be
enough to fix the order:

# chkconfig --del spamass-milter
# chkconfig --add spamass-milter
# chkconfig spamass-milter on

spamass-milter, spamassassin, and sendmail originally had the same
"start value" of 80, so they got started in alphabetical order. I
changed spamass-milter to 79 to get it to start before sendmail, but if
you already had spamass-milter installed then the order wouldn't get
changed. Starting spamassassin after spamass-milter isn't ideal but it's
not going to cause any big problem.
