Your A1 Web Server Control Panel
allows you to set up email filters.
In all honesty, filters will probably not be the ultimate
solution to your spam problem, but they may prove to be one of the tools you use
to build a complete solution.
In this tutorial, we will demonstrate how to set up a simple
filter to delete any email with the word DIET in the subject line.
The first step is to log into your cPanel and click on the
MAIL icon.

You should now be
looking at the Mail sub-menu. Click on the link which
say's "Email Filtering"

This will bring you
into the filters area.
To add a new filter,
click on the Add Filter link:

On this screen, you
will actually configure your filter using the two
pulldown boxes and the two text boxes you see below.
First, pull down the
first option box, as shown below, and select
"Subject".

Next, pull down the
second option box, and select "contains".

In the subsequent
textbox, type the word "DIET". In the lower textbox,
type the word "Discard".

You have now specified
a filter which will instruct the mail server to
discard any email which contains the word "DIET".
As you've probably
surmised, you can set up many various filters by
selecting various options and words.
To save this filter to
your settings profile, simply click the "Activate"
button as shown below.

As we mentioned,
filtering will probably not stop the bulk of your
spam. Spammers have simply become way too
sophisticated for filters to be very effective.
Our next lesson will
show you a much more powerful tool to use.
