Harry,
Did you comment out the following in /etc/rc2.d/S20mailscanner?
Code:
#check_dir /var/spool/MailScanner ${user:-mail} ${group:-mail}
#check_dir /var/lib/MailScanner ${user:-mail} ${group:-mail}
#check_dir /var/run/MailScanner ${user:-mail} ${group:-mail}
#check_dir /var/lock/subsys/MailScanner ${user:-mail} ${group:-mail}
If not, edit it so that it looks like the above and restart your system. Check your log and let me know if that worked.
Rocky
