Spam filter is a program that is used to detect unsolicited or unwanted emails and prevent those messages from getting to your inbox. The spam filter looks for certain criteria to make a judgment. It scans particular words in the subject line of the email, suspicious word patterns, or word frequency in the email body, as well as the attachments to block spam emails into your inbox.

The Email-Borne Threats:

On average, an office worker receives about 121 emails a day and among them, about sixty are spam emails.

The scary fact is that 5 out of every 60 emails can be phishing emails or emails containing malicious attachment including VIRUS, TROJAN or WORMS.

In case your system gets infected, some viruses are capable of hijacking your system and automatically send emails and infect the whole company.
