You can manage your filtering-preferences via the NETHZ user-services database
www.passwort.ethz.ch > meine Services > Email Spamfilter
By default, the mail filter refuses spam messages. To allow delivery of "tagged" spam messages, move your addresses from the "Spam-Mails verweigern" box to the "Spam-Mails mit
!SPAM: markieren" box.
Use the WHITELIST box to enter a sender address or domain that you wish to exempt from
spam checks.
Use the BLACKLIST box to enter a sender address or domain that you wish to have blocked.
Users are allowed a maximum of 100 whitelist & 100 blacklist entries.
Users may white-list or black-list individual sender addresses ([email protected]) or entire domains (gmx.ch).
Sender addresses in whitelists and blacklists use the envelope-from address, which is found
in the messageheader. This is not same as the "From:" address.
We recommend that users add domains to their blacklist (baidu.cn), rather than individual
addresses such as [email protected].
Domain entries in your blacklist & whitelist may contain a wildcard (*.cam.ac.uk, *.ru, *.biz,
*.com)
This whitelist domain entry: *.cam.ac.uk
would whitelist any domain ending with .cam.ac.uk
Examples:
o lists.cs.cam.ac.uk
o math.cam.ac.uk
o cam.ac.uk
This whitelist domain entry: *.edu
would whitelist any domain ending with .edu
Examples:
o mail.utexas.edu
o phys.harvard.edu
o mit.edu
 The effects of whitelist and blacklist entries may be combined:
o If you add a sender address such as [email protected] to your whitelist and add the aol.com
sender domain to your blacklist, this will allow you to receive mail from [email protected] but
refuse mail from any other aol.com address.
o If you add a sender domain such as gmail.com to your whitelist and add the *.com
sender domain to your blacklist, this will allow you to receive mail from gmail.com addresses, but refuse mail from any other address in a “.com” domain.

Messages from whitelisted senders contain an “X-User-Whitelisted-Sender” header.
Remember that messages matching a virus signature are refused without regard to user
preferences.
Changes to your filtering-preferences will become active within a maximum of 15 minutes.
The filtering service rejects entire messages; it does not remove “infected attachments”.
