Description of Spam Assassin

Its fast, it's easy to use and it's cheaper than postal route. Those messages which are sending to us will reside in our mail inbox.Sometimes, having an e-mail account can be very frustrating. People will fill our mail with advertisements, forwarded messages, product details, business offers, and all sort of unwanted junk. Separating the messages that we really want from the hundreds of unwanted mails is a daunting task. It may include both unsolicited and solicited mails. Those unsolicited mails are referred to as Spam mails. This process called Spamming makes many people really hate e-mail. But you are not powerless in the fight against unsolicited e-mail.For this reasons filters are introduced.

Mail filters in the server filters the Spam mails before they reach our inbox and mark them as Spam mails and it is send to our bulk folder. So we are prevented from reading those mails. If we use to respond for those mails more and more Spam mails will be sending to our inbox by the Spammers. When the sender of unsolicited e-mail offers to remove our e-mail id from their list, don't fall for it. This just confirms that our e-mail account is active, and we may actually receive more Spam. We can also do one thing, i.e. to send a message to our ISP or online service that we received unsolicited mail and to provide the originating address. In most cases, the return addresses are phony, but the service provider may be able to take action to stop the Spam.Many of the e-mail clients have special filters designed to block Spam. One among the best Spam filtering software is Spam Assassin, which is an Apache Software Foundation project and is released under the Apache License.
