Spam Filtering 2 - Expert Interface

This information is for employees (i.e. not for students) who use the Exchange server managed by Computer Services.

This assumes you have read "Spam Filtering 1" because you need to be logged into CanIt and have pressed the "Enable Expert Interface" button.

Don't fret. You don't need to be an 'expert' -- it's just the terminology CanIt uses.... We'll walk through exactly what you need.

What you need to know:
--Trap Contents holds 'trapped' spam messages
--Preferences is where you modify your settings
--Simplified Interface lets you go back to the basic choices

On the menu, select 'Preferences' then 'Stream Settings'



Let's walk down the screen to set this up.

At the top, in Filter Settings, change/set up "Automatically reject messages scoring more than this amount" to 10. Then set "Spam threshold" to 5.


What this means is that the really nasty stuff doesn't even get to CanIt, and messages that are questionable get held in the Trap Contents for you to look at. If you want. Or not.

You can tweak these numbers for your own comfort level. If you tighten it down too far, you do risk not getting some messages that you did want to get. Like I said, an art, not a science.

Go down to Tag Settings. Turn this off if you want spam to be held in CanIt, in the Spam Trap. You can change the text that gets put into the subject of messages if you want. But if you do that, and you set up Outlook Rules, you need to set your Rules according to what you set up here.


Ignore the next sets of things and now go to the bottom to Bayes Settings. This is the best since this is how you put some control on the spam as well as help teach CanIt that new variations are spam.

Couple of things to do here:
--YES, enable the Baysian analysis
--YES, enable the training
--add INLINE links to your emails to facilitate training

If you go to the trouble to click the "This is Spam" links in your email, that helps CanIt 'learn' that something is spam faster than it would on its own. Sometimes it feels like a nuisance to do but it's an investment in everyone's sanity.


At the beginning, check your Trap Contents so you see the sorts of messages that end up there. Click on Pending to see the list of messages.



I had to find a semi-benign message to show you want you can do with messages in the Trap. Hey, the stuff in my Spam trap is embarrassing, that's why it's there!

This is useful for messages that get stuck in the Trap but you really want to receive them. Tell CanIt to "Whitelist" the Sender (for a specific person), the Domain (for all senders from a specific email location) or the Network (for all messages from not only that address but related addresses).



Once you're comfortable with the settings, you can pretty much ignore it CanIt. Check your Spam Trap occasionally or if you think you're missing something and you're all set.

Again, click on "email" on the right and look for the "Outlook Rules" entry to get the messages tagged with [SPAM?] out of your inbox.
