Nowadays a highly reliable e-mail system have become a must for any organization in order to function. effectively These e-mail systems are under constant attack, plagued by Internet borne threats such as spams, viruses and phishing. Studies have shown that 70% to 95% of all e-mails sent are spam. Spam is unsolicited, unwanted, irrelevant, mass, and anonymous electronic correspondence.
Spam, in addition to the nuisance of consuming network bandwidth, also expends a lot of time for the users. Spam mails can also contain URL links to sites that may be known malware sources or phishing sites. One way to stop the flood of e-mail based inbound attacks are through the installation of an anti-spam flitering solution at the perimeter device such as a gateway, which can drop or flag the unwanted, malicious e-mail.
