= Spam Filter =
There are several spam filters who try to detect spam. They work in a row and each of them  may cause 'false positives' (mail detected as spam but is not spam). A typical row:
 1. Spam filter at the UZH mail server. Marked with '**-SPAM-**
 1. Spam filter in Zimbra (Math Departement). Marked with '#SPAMz#'
 1. Spam filter in the personal email program. Typical 'marked as spam'

 * Typically, all mail who is marked as spam by the UZH mail server (1) will be moved directly to the `Junk` folder. This happens through a so called 'sieve' filter on our mailserver.
 * Mails, who are detected as spam by Zimbra, are moved directly to the `Junk` folder too.

== false positives ==
Every Spam filter needs training from time to time. 
 * The UZH mailfilter will be maintained by the compute center and you have no direct influence to it. You are able to adjust a 'score' which is responsible to mark a mail as junk. In general this is not necessary.
 * The zimbra mail filter can be teached in the webinterface unter http://mail.math.uzh.ch.
  * select all mails which are junk and press 'Junk'.
  * False positives: mark all of them and press 'not junk'.
