By making use of Email Filters, it's possible to automatically sort through much of your inbox. The CSEE email server supports using sieve filters. You can either directly connect with a "managesieve" client, such as the Sieve Thunderbird Plugin, or using CSEE's webmail interface at webmail.cs.umbc.edu.

Using the Webmail Interface

This tutorial uses the new elastic CSEE skin, however the steps should be largely the same no matter the theme you are using. You can follow along with the video below or just read the instructions below it.

  1. Go into settings using the "gear" icon.
  2. Select "Filters"
  3. Use the "plus" icon on the upper right corner to create a new filter, or choose an existing filter to edit.
  4. Optionally, set a name for the filter under "filter name."
  5. Set a Rule for the filter. For example, "From contains gweiss@cs.umbc.edu" will apply whenever the sender's address contains "gweiss@cs.umbc.edu"
  6. Set an action for the filter. For example, "Move message to" allows you to automatically move the email to a given mail folder.
  7. Click on "save" to finalize the filter.

Default Filters

By default, two filters are present on your account. The first, "Send Spam to Junk," will send any detected spam emails to the junk mail folder. Our automatic detection is quite conservative so it is unlikely this will catch many false positives. The second is "Send Virus to Junk," which does the same but with malware or phishing links. Its recommended that you keep both of these on.

Advanced Editing

Our webmail client also allows editing of the direct sieve code rather than using the interface. While this is powerful, an incorrectly made sieve filter could cause you to lose mail, so be cautious when doing so.

  1. First, choose "actions."
  2. Now, choose "Edit Filter Set."
  3. This will open an editor containing all of your sieve filters. You are free to directly edit the script in the editor, or simply copy-paste code from elsewhere.

Note that sieve filters are organized into "sets", and only one "set" can be active at a time.
