It is an easy-to-use Microsoft Outlook add-on designed to provide an advanced intelligent protection against junk-mails, viruses, unsolicited emails. The program uses Bayesian filtering technology that identifies about 99% of incoming junk messages. QMailFilter seamlessly integrates into the MS Outlook, scanning all incoming emails. Emails identified as junk are moved to the Junk Email folder.

The virus filter is not based on large virus data bases but on rules, for example all emails with attachments containing double extensions, for example a zip file containing the file “your invoice.doc.exe” is deleted automatically, as well as all emails containing .pif files.

All words in all emails are examined against a data base containing probability of a word is a word frequently used in junk emails or frequently used in normal emails. The combined probability decides if an incoming email is considered as junk.

The rules based filter allows also to check the senders IP address against block lists or filter certain words out of the email.

After installation, you need to train the filter with your emails, for example the sent items and the inbox as at the one side and the junk mail and deleted objects at the other side. This way, QMailFilter will create the initial data base allowing it to find out if a given email is wanted or unwanted.

All new emails are now automatically moved to the Junk Email folder, if the filter did not recognize a junk or at the other hand recognizes a wanted email as junk, simply move it to the correct filter and re-train the filter. If the filter is already trained, it will examine only new emails.
