The toolbar contains red and green buttons to mark messages as spam or legitemate email.

Messages can be deleted or bounced back preventing viruses or large downloads doing any harm to your computer. The free version is available for use with just one email address only, and marks spam in red and trusted email in green.

A friend list ensures that Mailwasher does not block your friends email and a customisable blacklist and filtering tools provides automatic spam identification. Baysian filtering cleverly learns to identify spam more accurately and any dubious emails can be quickly previewd before downloading to your machine.

Mailwasher works in a different way to other spam filtering tools in that it attempts to block spam on the server side before it reaches your machine. When Mailwahser starts, messages identified as spam will be marked with a tick in the deleted column, which ensures they will be deleted from the server. You can then chose to uncheck any messages you feel have been wrongly identified as spam before hitting the process mail button. After you click the process mail button, all clean email will be downloaded to your email client saving you precious time reading through all those spam mails.

You may already have a free spam blocker and don't know about it

Most Internet Service Providers such as AOL and BT now incorporate some form of free anti-spam software for their customers.

If you are not sure if your Internet provider has a free spam filter, then check their homepage, or contact them for further information. You may not already be aware that some of you mail is being filtered and that sometimes spam filters can be a little bit too thorough. Therefore, it is important to know what mail is being blocked, to ensure that you are not losing any important emails to the spam filter.

Maybe your mail program can act as a free spam blocker?

For those who use outlook or outlook express, or some other email client, then you can usually set up a spam blocker using special rules to filter out specific word(s) which can appear in spam.

In outlook you should find these under the tools -> rules wizard menu. Failing this, search the help for rules on how to set up different filters.

However, a lot of spammers are aware of these procedures and will often alter words slightly, or pass messages in pictures in an attempt to thwart email filters.

Further Information

There are quite a few free ways to help prevent spam. Therefore, it is worth doing some research before finding one which is most suited to your needs, depending on the software you have, or the Internet provider you are using.

Some spam software and filters provided from Internet companies can be a little over zealous in blocking spams. Therefore, make sure you understand your software so that you don't inadvertently block, or delete, that all important mail.
