What is anti-spam?
The term anti-spam is used to refer to a software or to processes of detection and analysis that aim to block spam (or unwanted messages). The problem behind spams is that they often hide scams and threats. So what at first would be an unpretentious email may be hiding a phishing scam or a malware that is meant to steal information or hijack machines.
For businesses, in addition to the security issue, spam is also a risk because it can overwhelm servers, disrupt services and undermine business productivity, which, in the end, will lead to financial loss.
