Cannot set autoreply

Please tell me how to set autoreply

OS Centos6 MTA sendmail

/etc/mail/virtusertable test@xxxx.com tadao

And I have already worked with the information of 'https://www.virtualmin.com/node/14004'

"Email Messages" setting. Click the triangle and a list of four options should appear. Click on "Spam and Virus Scanning." Now on the right side, in the form that appears, look for the "Allow mailbox users to create mail filters?" setting. Click "Yes" and save that.

our /etc/procmailrc is following.

LOGFILE=/var/log/procmail.log
TRAP=/etc/webmin/virtual-server/procmail-logger.pl
MAILDIR=$HOME/Maildir
DEFAULT=$HOME/Maildir/
ORGMAIL=$HOME/Maildir/
DROPPRIVS=yes
:0
$DEFAULT

Login to Usermin by user tadao, and set autoreply.pl. The page shows followings.
