Spam Filtering ...
The problem with unsolicited email has been increasing over the years. Based on the volume and content of your own Inbox, you would probably agree that it is reaching overbearing proportions. Arabnix is now expanding on the possibilities to filter unwanted or junk email using SpamAssassin and other Open Source tools.
SpamAssassin:
SpamAssassin uses established rules and tests for determining if an email matches similar characteristics of “spam” (unsolicited commercial email.) Such rules and tests examine the message content and headers and assign a numeric score for each matching feature. The message may then be filtered based on this score, where the higher the score the more likely the message is spam.
SpamAssassin processes mail at the server, marking messages as spam based on certain tests (such as using foreign language characters in the email, or containing certain words.) Upon marking the message as spam, it may be passed on to you (so that you may filter it yourself in your mail client), redirected to a ’spam mailbox’ on the server (so you may later review it and see if any legitimate mail was sent there), or deleted completely.
Worried about legitimate email being caught by SpamAssassin? It’s possible to “white list” email based on the senders address. We can set it so all email from this sender will arrive in your Inbox, no matter what the spam score of the message might otherwise be. Or, you can assign email from the sender a negative score (lowering the chance it is marked as spam) in case a spammer forges an email address, making it look like the spam came from a user you know.
