Webmail Tools: Spam Filtering on RCI

Using Your Spam Filter

Spam is a name for unwanted email, usually advertisements. The RCI Spam Filter uses a complex scoring system to filter out these emails using characteristics commonly found in spam (e.g., a subject line that includes the word "Viagra"). Until you are sure that the spam filter is not filtering out messages that you actually want to receive, you will need to periodically review the messages in the spam folder.

Setting Up Spam Filtering

  1. Go to the following URL: https://webmail.rci.rutgers.edu. All mail tools are accessed through the SquirrelMail webmail program.
  1. Enter the user name (NetID) and password from your RCI e-mail account in the Name and Password login boxes, and then press login.
  1. Select the Webtools link at the top of the screen.
  1. Under Setup, click on the spam filtering link.
  1. Select Setup spam filtering from the two options provided.
  1. If this is your initial attempt at using the spam filter, skip Section 1 and scroll down the page to Section 2. Check the box next to "Store the spam in a folder named AUTO-DELETED-SPAM."
  1. It is not necessary to change the Spam filter level at this point. The default is 7 and can be changed at a later time if you find that the filtering level is inadequate.
  1. When you are finished, simply click the Submit button. You will receive confirmation that your spam filter has been activated.

Reviewing Auto-Deleted Spam in Netscape Mail or Thunderbird

  1. Login to your email account as you would normally.
  1. If you do not see the AUTO-DELETED-SPAM folder in your list of folders, select File - Subscribe from the pull down menus at the top of the screen.
  1. If INBOX is the only subscribed folder you see, click on the arrow to the left of INBOX to expand the folder list.
  1. Check the box next to the AUTO-DELETED-SPAM folder and select the Subscribe button.
  1. Click the OK button and you should now be able to see the folder in your folder list. If you get an error message indicating that "The current command did not succeed. The mail server responded: Cannot subscribe to this folder." please follow steps 1 to 4 under Setting Up Spam Filtering, then select Disable Spam Filtering and contact your PC Coordinator for additional assistance.
  1. You can also review your AUTO-DELETED-SPAM in SquirrelMail (the current version of Webmail) by selecting the folder name from the list at the left side of the screen.

    Every night, all of the messages in the AUTO-DELETED-SPAM folder that are older than two weeks are automatically deleted. You can, of course, delete the messages in this folder yourself more frequently.

    If you find that there are messages in your AUTO-DELETED-SPAM folder that you do not consider spam, make note of the email address (e.g., jsmith@rutgers.edu) or the domain name (e.g., rutgers.edu) and follow the instructions below for Editing your Spam Filter.

    If you find that too much spam is getting through to your Inbox, follow the instructions below for Editing your Spam Filter.

Editing your Spam Filter

  1. Follow steps 1 to 5 under Setting Up Spam Filtering above.
  1. Once you have identified an email address or a domain that you DO NOT want filtered out as spam, enter that complete address or domain in the appropriate box in Section 1. Make sure to enter the information in one of the boxes labelled "NEVER treat mail from this…" This will insure that ALL mail from that source will reach your Inbox and not be filtered out as spam.

    If you can identify an email address or domain that consistently sends you spam (and NEVER sends you legitimate email), you can enter that information in one of the boxes labelled "ALWAYS treat mail from this…" This will insure that NO mail from that source will reach your Inbox.
  1. To increase the filter level to send more messages to the AUTO-DELETED-SPAM folder, scroll down the page to Section 2 and use the pull down menu to change the Spam filter level to a lower number. The lower the number, the stricter the filter.
  1. When you are finished making all of your planned changes to the filter, simply click the Submit button. You will receive confirmation that your spam filter has been activated.

Disabling Your Spam Filter

  1. Follow steps 1 to 4 under Setting Up Spam Filtering above.
  1. Select Disable spam filtering. You will receive confirmation that your spam filter has been removed.

    Please note: If at any time you Disable spam filtering your edited settings will be lost. If you decide to Setup spam filtering again at a later time you will have to start over from the default spam filter settings.
