Spam Filtering for RAMS.

Spam filtering basics.

Support has been added to RAMS to take advantage of the university's SpamAssassin boxes. All mail coming into RAMS gets scanned by SpamAssassin and assigned a spam score. The higher the score, the more spam-like the message. Something with a score of 10.0 or more is extremely likely to be spam. Something with a score of 6.0 is probably not spam, but might be. Something with a score of 4.0 or less is very likely to not be spam. When RAMS filters a message as spam, it does not delete the message, but simply treats it differently depending on what type of list you have as detailed below.

Activating and setting spam filtering.

The procedure to turn on spam filtering and set your spam threshold value is the same for every type of list. First you must log into the list editor using your NetID. Once logged in, you must select the list you whish to adjust your spam settings for. Once the list is selected, you then select "Manage Spam Filters" from the task selection pull-down list and click the "select task" button. You should then be presented with the screen for managing your spam filter settings. On the spam filter settings page, set "Spam Filter" to "ON", and put a number in the "Enter Spam Threshold" field. We recommend a setting of 6 or 7 depending on the type of spam you are getting. A setting of 5 or lower runs a definite risk of catching non-spam mails. RAMS defaults to 7.

Spam filtering effects for moderated lists.

For moderated lists, all messages must go through the moderator. Messages that exceed the spam threshold will not get forwarded to the moderator via email. instead, it will just be submitted to the moderation queue (normally, both would be done). Additionally, the moderation/primetime page will hide all messages exceeding the spam threshold. To see these messages, click the button labeled "show spam messages." When you are tired of looking at them, you can click the button labeled "hide spam messages."

Spam filtering effects for closed lists.

For closed lists, only members of the list can post to the list. Should any spam be sent to the list that will pass the membership check but still exceed the set spam threshold, it will not be forwarded to the list. However, it will not be deleted. What will happen is it will be inserted in the moderation/primetime queue for the list. The list owner, moderator, editor, and creator can view the message on the moderation/primetime screen and release it to the list should they so desire. For closed lists, the moderation/primetime screen defaults to showing spam messages since that is the only thing that screen is used for.

Spam filtering effects for open lists.

For open lists, anyone in the world can post to the list. Should any spam be sent to the list that exceeds the set spam threshold, it will not be forwarded to the list. However, it will not be deleted. What will happen is it will be inserted in the moderation/primetime queue for the list. The list owner, moderator, editor, and creator can view the message on the moderation/primetime screen and release it to the list should they so desire. For closed lists, the moderation/primetime screen defaults to showing spam messages since that is the only thing that screen is used for.
