How to use the SPAM folders feature (declare SPAM)
The new SPAM folders filter feature allows each user to declare SPAM directly and customise the anti-spam service to their personal needs. The feature is enabled on a server by server basis, so if you would like the feature enabled on your server, please ask us.
How it works
The following folders will automatically appear in your Inbox once we enable the feature. Once they are created they behave just like any other folder except that you do not have permission to delete them. You can, however, unsubscribe from them, but quarantined mail will still be delivered into them.
When an email arrives at the server, the server carries out a series of tests, and based on those tests, certain actions are taken. The email may be rejected if it is coming from a known spam source (aka blacklisting). It may be temporarily delayed by five minutes if the source is unknown (based on the previous 30 days' traffic)(aka greylisting). It may be silently deleted if it is a virus. It may be quarantined if the server feels sure it is spam, and it may be delivered as normal but tagged if the server thinks it may be spam but isn't sure. If a message passes all of these tests, it is delivered as normal.
spam-quarantine folder
Any message detected as SPAM will be delivered into spam-filter/spam-quarantine and will be automatically deleted after one month. This allows you to check the folder in case the server was mistaken (aka a false-positive). If you find an email that has been flagged incorrectly as spam, all you have to do is to copy (not move) it into the declare-as-not-spam folder, and move the original into your Inbox (or wherever you want to file it).
declare-as-spam folder
Any SPAM message moved into this folder by the user will be processed by the server each night, and then deleted. It will use that email to vary the rules it uses to analyse future emails, so over a period of time, the system will become more accurate. Once the server has processed a message, it is automatically deleted.
declare-as-not-spam folder
Any quarantined emails (which will have ** SPAM ** prefixed to the subject) which are copied into this folder will be processed by the server each night, and then deleted. It will use that email to vary the rules it uses to analyse future emails, so over a period of time, the system will become more accurate. Once the server has processed a message, it is automatically deleted. If you find an email that has been flagged incorrectly as spam, all you have to do is to copy (not move) it into the declare-as-not-spam folder, and move the original into your Inbox (or wherever you want to file it).
Emails with "POSSIBLE SPAM" in the subject
Emails which the spam filter only thinks are spam will have their subject changed to add "POSSIBLE SPAM" along with a spam score. This leaves it up to you to confirm message as either spam (by moving it to the "declare-as-spam" folder) or not spam (by copying it to the "declare-as-not-spam" folder).
