Spam Filtering


Overview

The mail server for Mathematical Sciences marks messages that it determines to be spam. For any message found to be spam, the string [SPAM?]-, immediately followed by a numeric spam score, is prepended to the Subject: header. Also, a footnote that includes a report of the spam scoring is appended to the body of the message. The altered Subject: header can be used to filter spam.

You can set up either a server-side filter on the email server, or a client-side filter in the application that you use to read your email. The advantage of server-side filtering is that you only need to create one filter, and it will run regardless of whether you are logged into the mail server. If you use Mathematical Sciences Webmail or email clients configured with the IMAP protocol, you can use server-side filtering to move spam into a separate folder. If you use only email clients configured with the POP protocol, you can still use server-side filtering for other issues, but you will not be able to create a spam filter that moves spam into a separate server-side folder.
