| Challenge
Response
Challenge Response feature is very
effective against spammers. It has to be enabled
by the administrator of Mail Server but in case
user has it enabled by administrator the WebMail
lets user to manage his/her personal Challenge
Response settings and authorize messages or to
assign any action to any sender. e.g. reject messages
from spammer@penteldemo.com, etc.
Challenge Response system engine
receives messages and doesn't deliver the message
to the user's mailbox until the sender of message
is authorized. There are two ways of authorization:
- sender can be authorized by user
- sender can authorize himself/herself by going
to generated web page and copying special code
there
Challenge Response engine generates
a special web page to any received message from
sender who is not authorized already. And it generates
also special message to sender where the URL of
such web page is written so sender can authorize
himself/herself.
If user wants to authorize any sender
or any pending message, WebMail allows a great
interface for this.
Once you are in the webmail, go
to "settings" and then go to "Challenge
Response." The screen will appear showing
you any mail that is considered spam on the Pentel
Net server.
The top of this dialog allows user to choose which
messages/senders should be shown and user can
also specify any word in Search sender field and
then only senders containing specified word will
be shown.
In the table the senders/messages can be selected
and user can choose the action which should take
place:
Of course, any record can be deleted too.
The bottom part of dialog allows user to easily
change the Action which is assigned to particular
sender.
Senders can be loaded also from file. The structure
of file has to be one address per line.
