 Minimising Spam Emails/Utilising Server Rules

Junk email (also known as spam email) is a form of unsolicited email that is usually sent out in bulk to promote various products, services, and complete garbage to anyone who advertises their email address anywhere online (and to a lesser extent offline). Given this scenario, junk email is very hard to avoid completely although can be cut down drastically by utilising the Server Rules section of the Web Mail facility.

Upon logging in to Web Mail, please click on the Settings tab outlined in the screenshot below (please note that this may appear slightly different depending on the theme you have selected):

Next, click on the Server Rules link on the left to bring up the following screen:

There are two modes of Server Rules you can utilise within Web Mail: Basic View and Advanced View. For any Server Rules to be active, you need to ensure the Enable tick box is ticked. Here is a rundown of the following sections of the Server Rules page taken from the Ice Warp help article and how they can be applied to your email account to help minimise spam, along with various other options. Some options only appear in specific views:

Reject - Rejects the message so the message will not be received and all following filters will not be processed.

Accept - This action clears the spam flag and immediately accepts the message and all following filters will not be processed. It is a white listing action.

Delete - The delete action is something between the Reject and Accept. It does not accept and deliver the message but also does not reject it. It accepts the message but does not return any false response and does not deliver it.

Mark as spam - This action sets the Spam flag of the message so it will be processed according to the Instant Anti Spam settings of the user.
