SpamAssassin on mail.pa.msu.edu

Part 1: How to get it and what you'll see once you have it

  1. Problem

    You want spam E-mail to be automatically moved out of your Inbox.

  2. Solution

    Contact helpdesk@pa.msu.edu to have your E-mail routed through the SpamAssassin program on its way to your Inbox.

  3. Other Useful Information

    We can set up SpamAssassin for you with a minimum of fuss:

    • if you don't forward your E-mail elsewhere;
    • if you don't already use another server-based E-mail filter
      (if you don't know what this means, you probably don't); and
    • if your IMAP E-mail client is configured correctly to use your "mail" sub-directory to store your E-mail.

    If one or more of these conditions is not true, we can still set up SpamAssassin for you, but we will have to consult with you about the procedure for handling the exception(s).

    When SpamAssassin is set up in its default mode, you will have three additional "Inbox"-type E-mail folders:

    • IN.probable-spam
      (messages which have some characteristics of spam E-mail)
    • IN.spam
      (messages which have even more characteristics of spam E-mail)
    • IN.probable-virus
      (messages with certain characteristics of known E-mail-carried viruses)

    There is some overlap between the characteristics sought for to signal virus content and those which signal spam, so some spam messages may end up in the IN.probable-virus folder, and some viruses may end up in one of the spam folders.

    No filter is perfect, so some spam will still end up in your Inbox. Looking at it in "full headers" mode, you will see an "X-Spam-Status:" header containing the score assigned to it by SpamAssassin when trying to decide spam/non-spam. Some spammers intentionally aim for making their spam messages look as much as possible like ordinary E-mail, and sometimes they succeed. SpamAssassin does have "learning" capabilities, so some messages which are not caught when you first start using it would be caught later on (more on this in FAQ #3 - see the Links section, below).

    Some desired E-mail (usually from mailing lists or from companies with which you have wanted dealings) may end up classified in one of the spam folders. SpamAssassin has a "whitelist" capability to cause SpamAssassin to not count messages from known senders (on the list) as spam. This will be described in FAQ #4. When it is written, a link will appear on this FAQ.
