Reporting Spam to ZSD

ZSD has a service for reporting spam. Users can send spam that they have received to a special spam reporting address as described below. We use these messages in our efforts to improve our anti-spam filters.

Spam Reporting Address

ZSD provide an e-mail address to which users can send reports of spam. This address is "". Please note the following with regards to spam reports:

How to Report Spam with Full Internet Headers

In order for ZSD to use your spam for updating our filters we need to be able to see the "Internet Headers" of the reported messages. These are usually lost when forwarding a message. Different mail clients have different means of forwarding messages, with all of the headers. The following one works with most modern desktop mail clients:

  1. Set the size of your e-mail program so that it is not "maximized'. Ie it only occupies a portion of your desktop, not the whole desktop. It should also not be "mimimized" - ie not just an icon in your task bar.
  2. Open your "inbox" where the offending spam message is listed.
  3. Create a new blank message. Address it to "". You should also put something descriptive in the subject line. The size of the new message window should also occupy just part of your desktop.

  4. Drag the spam message from your inbox over the new message that you have created. The message should be added as an attachment to the new message. This attachment will be sent with all the internet headers.
  5. Repeat the above if you want have multiple spam messages in your inbox that you would like to report.
  6. Send the final message to ZSD.

How many messages should you report?

Privacy Considerations

Any mail you submit to our spam reporting system will contain you own e-mail address and it may contain other personal information.

Spam reports filtered by ZSD's spam filters

The spam reporting address is white listed from ZSD's spam filters. However it is not white listed from our anti-virus filters. Thus the mail should be accepted by ZSD, even though it contains obvious spam. However sometimes our anti-virus filters identify spam report messages that are actually "spam" as "viruses" and bounce them. This is an unavoidable side effect. If you pick up this problem on regular, recurring basis, please forward the bounce message to ZSD so that we can investigate.

How do we use spam reports

ZSD may use your spam reports as follows:

  1. To keep track of the type and volume of spam received by our users.
  2. As a reference to determine what kinds of mail our users regards as spam.
  3. As examples to justify our policies to block various sources of mail as spam.
  4. As samples to investigate specific "waves" of spam.
  5. As samples to investigate and test new anti-spam technologies.
  6. As a mechanism for getting specific spam reports from clients.
  7. For training "automatic learning" anti-spam software.
  8. The reported messages are kept in a database for a period of time (typically 2 years), although some reports may be kept for longer periods.
  9. Messages which lack internet headers, duplicate samples of the same spam and messages which are not useful for the above purposes are deleted.
  10. ZSD will NOT attempt to "unsubscribe" you from the spammer's database.
