As a busy administrator, you know Spam is a major distraction in todays network. The effects range from inappropriate content arriving in the mailboxes up to contact email addresses placed on a website being deluged with unsolicited mail, causing valid enquiries and sales leads to be lost and wasting employee time.
In response to the growing problem of spam, a number of free and commercial applications and services have been developed to help network administrators and email users combat spam. Free to use, flexible, and effective, SpamAssassin has become the most popular open source antispam application.
