IMPORTANT: the White Listing with Ask that is described on this page is no longer supported on the departmental E-Mail servers.
This description is left here only for historical/archive reasons.
White ListingWhite Listing is a technique to build a list a mail senders allowed to send you mail. Senders not in your whitelist can send you mail, but need to register in your whitelist before their mail reaches you.
This technique can be used e.g. to prevent spam sent from unusable email addresses to reach you.
This text describes the setup for cs.kuleuven.be.
We use Ask in combination with procmail
- Procmail is allready installed on our machines and is e.g. used for "Vacation/Out with Office" messages.
- Procmail can be used to handle part of your email (e.g. by throwing away Spam recognized by our anti-virus and anti-spam host dr-zook).
- By calling Ask from your .procmailrc one can implement different strategies.
The setup of ask in integrated into setup_procmail.
- If you did choose automatic setup, no questions will be asked for
- If you did choose normal
setup check here for the possible options.
- If you did choose guru setup you can use the manual setup description as a guidelin
( This mail must be sent with the appropriate signature. see "rc_mailkey point 3 above".)
The answer :
ASK understands several commands. All these commands are issued by sending mailThis can and must be used to clean up your .ask/queue directory:
to yourself with special subjects. These subjects are:
Returns this message
ask process queue
Sends you a list of mail in your queue and lets you act on them
ask edit whitelist
Allows you to edit your whitelist
ask edit ignorelist
Allows you to edit your ignorelist
For "subject: ask process queue" Ask will send back a mail with a short description of every mail in the ask queue:
...Each description is preceded bij a action tag (e.g. N or R). Messages older than rc_remote_cmd_max_age days (default 10) will have a R (remove).
ASK QUEUE REPORT
These are the contents of your ASK queue. These emails are sitting in the
queue waiting for a confirmation from the sender. Change the "N" on the left
of each email with the desired action. Actions are:
N - Do Nothing. Leave it queued.
R - Remove from queue.
D - Deliver message (but don't whitelist sender).
W - Deliver AND Whitelist sender.
I - Add sender to Ignorelist (and delete message).
Just edit the message as you wish and reply. Quotes are OK.
