The same thing occurred when I just upgraded from 4.80.7 to 4.80.9.

This time I was able to determine that the change in ownership occurred
when I ran

  service MailScanner restartms

>From that, I was able to determine that the problem is in
/etc/sysconfig/MailScanner. Line 56 is

RANAS=`$CMD -e "print
MailScanner::Config::QuickPeek('$MSCONF','RunAsUser')"`

and should be

RUNAS=`$CMD -e "print
MailScanner::Config::QuickPeek('$MSCONF','RunAsUser')"`

i.e. it sets RANAS, not RUNAS.

In detail what happens is /etc/init.d/MailScanner sets RUNAS=root and
then sources /etc/sysconfig/MailScanner.

/etc/sysconfig/MailScanner erroneously sets RANAS and then later does

if [ "x$RUNAS" = "x" ]; then
  RUNAS=postfix
fi

but RUNAS was previously set to root by /etc/init.d/MailScanner so it
remains set as root.
